1. 

M is the father of N who is the son of V. In order to know the relation of M to P, which of the statement/statements is/are necessary?

1. P is the brother of V.

2. The daughter of N is the granddaughter of V.
A. Only (1)
B. Only (2)
C. Either (1) or (2)
D. (1) and (2) both

Answer: Option A

Explanation:

M is the father of N and N is the son of V.

Hence, V is the mother of N.

From (1), P is the brother of V

Therefore, M is the brother-in-law of P because V is the wife of M. From (2), the daughter of N, is the granddaughter of V. From this we do not get any relation of M to P.
