Correct option is C
Step 1: Analyzing Given Information
- A is the son of P and brother of V → A and V are siblings.
- N is the sister of V → So, A, V, and N are siblings.
- S is the nephew of V → Since S is the nephew of V, S must be the son of A or N.
- B is the daughter-in-law of A → This means B is the wife of A’s son.
- M is the mother of N → So, M is the mother of A, V, and N.
- We need to find how B is related to M.
Step 2: Understanding the Relationship
- A, V, and N are siblings.
- M is the mother of A.
- A has a son (since B is his daughter-in-law).
- B is the wife of A’s son, meaning she is A's son's wife.
- A is the son of M.
- This means B is the wife of M’s grandson.
Thus, B is the Grandson’s wife of M.
Final Answer:
(c) Grandson’s wife.
