In a code, 'A # B' means 'A is the mother of B', 'A * B' means 'A is the brother of B' and 'A @ B' means 'A is the daughter of B'. In the expression 'A @ B * C # D', how is D related to A?
D is the cousin of A. A is the daughter of B, and B's sibling C is the mother of D. A's father and D's mother are siblings, so A and D are children of siblings and are therefore cousins.

Explanation
A @ B means A is the daughter of B, and B * C means B is the brother of C. So C is A's paternal aunt. C # D means C is the mother of D, so D is the child of A's aunt. The children of a father's sister are cousins. Nephew is wrong because D is not the child of A's sibling.
