Detailed Solution & Explanation
1. 'my nephew': A's sister's (or brother's) son. Since the question specifies 'A's sister who has no sister', A's sister is the only sister of A, so the nephew must be the son of this sister.
2. 'nephew's maternal grandmother': The maternal grandmother of A's sister's son is A's sister's mother.
Therefore, the woman in question is the mother of A's sister.
Note: The textbook answer key contains a typographical error marking this as Option A (Cousin). The correct option is Option C (Mother).
Hence, **Option C** is the correct answer.
