[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.
