Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.

Statements:
I. No B is A.
II. No C is B.

Conclusions:
I. No C is A.
II. No A is B.
III. Some B are not C.

Conclusion: I. No C is A.

There is not any direct relationship between C and A. So the given conclusion does not follow.

Conclusion: II. No A is B.

The given conclusion follows. Because there is a completely negative relation between them is given in the venn diagram.

Conclusion: III. Some B are not C.

The given conclusion follows. Because there is a completely negative relation between them is given in the venn diagram. So the relation of 'some not' will be definitely true.

Hence both conclusions II and III follow.
