How is T related to K?

I. K has two sons; one of the sons is A.

II. The mother of T has only two sons - A and B


A) if the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question

B) if the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question

C) if the data either in statement I alone or in statement II alone are sufficient to answer the question

D) if the data given in both statement I and II together are not sufficient to answer the question

E) if the data in both statements I and II together are necessary to answer the question

Answer:

Option E

Explanation:

From II, we know that T's mother has only two sons, A and B. This implies that T is the sister of both A and B. But, from I, A is also K's son. So, T is the daughter of K.
