   Correct answer: (D) Uncle

   B's mother's daughter = B's sister (or B herself). A's mother = B's sister. So B is A's maternal uncle... B is A's maternal aunt/uncle. If B's mother's daughter = B herself, then A's mother = B, making B A's mother. But if daughter ≠ B, B is A's maternal uncle. Most likely: B is A's uncle.
