Show answer & explanation
Correct answer: C
From the expression: N is daughter of M (N ⊕ M), M is wife of P (M ⊙ P) and P is father of Q (P $ Q). So M is mother of Q and N is sister of Q; P is father of N by virtue of being M’s husband. L is husband of N, therefore L is brother-in-law of Q, not Q’s brother — so statement (3) is incorrect.
