From the venn diagram, we can see that only conclusions I and IV follow.
Hence, option B is the correct answer.

Let us evaluate the options.

Option A:

Judge, thief, criminal

All thieves are criminals. Therefore, the circle representing thieves must be completely present within the circle representing criminals. No such circle is present in the given image. Therefore, we can eliminate option A.

Option B:

Tea, coffee, beverages

Tea and coffee are beverages. Tea and coffee must be represented by 2 non-intersecting circles. These 2 circles must be present completely within a larger circle. Therefore, we can eliminate option B as well.

Option D:

Cabinet, minister, home-minister

Ministers are present in the cabinet. Home-minister is minister who holds a particular portfolio (looks after internal affairs). Therefore, option D should be represented by 3 concentric circles. We can eliminate option C as well.

Option C:

Males, Fathers, Doctors

All fathers must be males. Therefore, the circle representing fathers must be present entirely within the circle representing the males. Some males and some fathers are doctors. Males, who are not fathers, can be doctor as well. Females can be doctors as well. Therefore, the circle representing doctors should intersect the circles representing both males and fathers. These things are represented perfectly by the given diagram and hence, option C is the right answer.

On drawing the Venn diagram

It is given that TCS has a total of 42 business analysts covering at least one of the three locations: Singapore, New York and London.

Therefore, (12 – x) + (14 – x) + (12 – x) + 6 + 4 + 8 + x = 42

$\Rightarrow$ 56 – 2x = 42 i.e. x = 7.

Therefore, the number of analysts covering New York alone = 14 – x = 14 – 7 = 7.

Everyone who is sane can do logic and all who can do logic are fit to serve on a jury. So, all who can do logic are fit to serve on a jury.
Hence, option B is the correct answer.

Nothing uncertain is worth dying for. and all beliefs are uncertain. So, no belief is worth dying for.
Hence, option D is the correct answer.

All students of this college rank as University students and all University students are eligible to enter for the prize. Therefore, all first year students are entitled to enter for the prize.
Hence, option C is the correct answer.

ADF is false as we cannot infer F(Some mammals are whales.) even if A(Some mammals are carnivores.) and D(All whales are carnivores.) are true.

ABC and  AEF all statements are different, the set is not related.

All whales are mammals and all whales are aquatic animals. So, some aquatic animals are mammals. Therefore, BCE is valid combination.

Hence, option D is the correct answer.
