The question below is followed by two statements numbered I and II. Decide whether the data given in the statements are sufficient to answer the question.
B is the brother of A. How is A related to B?
I. A is the sister of C.
II. E is the husband of A.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Either statement I alone or statement II alone is sufficient.
B is A’s brother, so A is B’s sister if A is female and B’s brother if A is male. The question is answered by anything that fixes A’s gender.
Statement I alone (A is the sister of C):
A is a sister, so A is female and A is B’s sister: sufficient
Statement II alone (E is the husband of A):
A has a husband, so A is female and A is B’s sister: sufficient
