From the diagram, we can see that all tables can be chairs. Hence, conclusion II follows.
Therefore, option C is the correct answer.

From the diagram, we can see that all pencils can be markers hence conclusion I follows.
No pen is a pencil and all pens are markers. Hence, all markers can’t be pencils. Thus, conclusion II doesn’t follow.
Therefore, option A is the correct answer.

Since some bikes are cars and no car is a boat, all bikes cannot be boats. Thus, conclusion I is not possible.
Since some bikes are boats and no car is a boat, all bikes cannot be boats. Thus, conclusion II follows.
Hence, option B is the correct answer.

Since some doctors are engineers and no engineer is a journalist, all doctors cannot be journalists. Thus, conclusion I is not possible.

From the venn diagram, we can see that conclusion II is possible.
Hence, option B is the correct answer.

Since some students are teacher and no girl is a teacher, all students cannot be girls. Thus, conclusion I is not possible.

From the venn diagram, we can see that conclusion II follows.
Hence, option C is the correct answer.

From the diagram, we can see that some triangles can be circles hence, conclusion I doesn’t follow.
From the diagram, we can see that some circles can be pentagons hence, conclusion II follows.
Therefore, option B is the correct answer.

Some bats are caps and no cap is a wicket. So, all bats cannot be wickets. Thus, conclusion I is not possible.

From the venn diagram, we can see that conclusion II is possible.

Hence, option B is the correct answer.

From the diagram, we can see that some rubbers can be pencils hence conclusion I follows.
From the diagram, we can see that some books can be pencils hence conclusion II doesn’t follow.
Therefore, option A is the correct answer.

From the diagram, we can see that some grapes can be mangoes hence, conclusion I doesn’t follow.
From the diagram, we can see that some mangoes can be bananas hence, conclusion II follows.
Therefore, option B is the correct answer.

Venn diagram for option A:

From the venn diagram, we can see that only conclusion II follows.

Venn diagram for option B:

From the venn diagram, we can see that only conclusion II follows.

Venn diagram for option C:

From the venn diagram, we can see that only conclusion II follows.

Venn diagram for option D:

From the venn diagram, we can see that only conclusion II follows.

Venn diagram for option E:

From the venn diagram, we can see that both the conclusions follow.

Hence, option E is the correct answer.

From the venn diagram, we can see that all the conclusions follow.

Hence, option D is the correct answer. From the diagram, we can see that some pebbles are definitely bricks. Hence, conclusion I follows.
From the diagram, we can see that some stones are definitely cubes. Hence, conclusion II follows.
From the diagram, we can see that some stones are definitely bricks. Hence, conclusion III follows.
Hence we can say that option E is correct.

From the venn diagram, we can see that conclusion I follows.
Also, some roubles are euros and no dollar is a rouble. Thus, all euros cannot be dollars. Therefore, conclusion II does not follow.
Hence, option A is the correct answer.

From the diagram, we can see that some fruits can be Japanese. Hence, conclusion I follows.
From the diagram, we can see that some veggies can be Japanese. Hence, conclusion II follows.
All fruits can be Japanese. There is no restriction on that part. Hence conclusion III doesn’t follow.
Therefore, we can say that option C is correct.

From the venn diagram, we can see that conclusion I follows. Also, all rivers cannot be oceans because some rivers are ponds and no pond is an ocean. Thus, conclusion II also follows.
Hence, option C is the correct answer.

We can see that all pens can be boxes. Hence conclusion I follows.
We can see that no marker can be protractor. Hence conclusion II doesn’t follow.
Thus option A is the correct answer.

From the venn diagram, we can see that conclusions I and II are possible and conclusion III is not possible. Hence, option B is the correct answer.

We can see that some cones have to be cubes. Hence, conclusion I follows.
We can see that some circles can be cones. Hence, conclusion II follows.
Therefore, option C is the correct answer.

One of the possibilities of option A can be represented diagrammatically as follows: As we can see, we cannot infer any of the conclusions. Therefore, we can eliminate option A.
Option B can be represented diagrammatically as follows without violating any of the conditions: As we can see, we can infer only conclusion I. Conclusion II cannot be inferred. Therefore, we can eliminate option B as well.

Option C can be represented diagrammatically as follows: Only conclusion II can be inferred from option C. Conclusion I cannot be inferred from the diagram given above. Therefore, we can eliminate option C too.

Option E can be represented diagrammatically as given below: Neither of the conclusions can be said to be definitely true. Therefore, we can eliminate option E.

Option D can be represented diagrammatically as follows:

As we can see, bees that are wasps are flies. Therefore, some bees are flies. Conclusion I is definitely true.
All wasps are ants. Therefore, conclusion II is also true. Both the conclusions are true for the statements given in option D. Therefore, option D is the right answer. Option A can be represented diagrammatically as follows: Both the conclusions are possibilities. We cannot say either of the conclusions to be definitely true. Therefore, we can eliminate option A.

One of the possibilities of option B can be represented diagrammatically as follows: As we can see, none of the conclusions can be inferred from option B.

Option C can be represented diagrammatically as follows:

Only conclusion II can be definitely said to be true. Conclusion I may or may not be true. Therefore, we can eliminate option D as well.

Option E can be represented diagrammatically as follows:

Option A can be represented diagrammatically as follows:

As we can see, we cannot ascertain that all highs are lows. Therefore, we can eliminate option C as well.

Option D can be represented diagrammatically as follows:

We cannot say with conviction that all highs are lows. Therefore, we can eliminate option E too.

Option B can be represented diagrammatically as follows:

On drawing all possible cases,

We can see that some erasers may or may not be books. Hence conclusion I doesn’t follow.

Since all pencils are erasers and some pens are pencils therefor some pens has to be erasers. Hence conclusion II follows.

Thus option B is the correct answer. Venn diagram for option A:

Venn diagram for option B:

Venn diagram for option C:

Venn diagram for option D:

Venn diagram for option E:

Hence, option B is the correct answer.
