Show answer & explanation

Correct answer: C

Interpret the chain step by step: A % B → A is son of B (so B is a parent of A).

B ⊕ C → C is husband of B (so B and C are spouses).

C Δ D → C is father of D (so D is child of C and hence child of the couple C–B).

Since B and C are husband and wife and C is father of D, B is the mother of D. A is son of B (and since B’s husband is C, A is also child of C). Thus A and D are children of the same parents → they are siblings. A is male (given “son”), so A is brother of D.
