A Correct answer
Explanation

If A's son is D's brother, then D is A's daughter (since D is female). C and D are sisters, so C is also A's daughter. Since A and B are brothers, B is A's brother, making B the uncle of C (his brother's daughter). The key is recognizing that A is the father of both D and C, and B being A's brother makes him the uncle.
