In a code, 'P $ Q' means 'P is the mother of Q', 'P & Q' means 'P is the husband of Q' and 'P ~ Q' means 'P is the brother of Q'. In the expression A ~ B $ C & D, how is A related to D's husband?
A is the maternal uncle of D's husband. A is the brother of B, and B is the mother of C. A is therefore C's mother's brother. C is D's husband, so A is the maternal uncle of D's husband.

Explanation
A ~ B means A is the brother of B. B $ C means B is the mother of C. So A is the brother of C's mother, which makes A the maternal uncle of C. C & D means C is D's husband, so C is D's husband. A is therefore the maternal uncle of D's husband. 'Paternal uncle' is wrong because B is C's mother, not father.
