Detailed Solution & Explanation
Let's analyze the statement: 'His mother's only daughter is my mother.'
1. 'His mother's only daughter': The mother of the man in the photograph's only daughter is the man's sister.
2. 'His mother's only daughter is my mother': Substituting the sister of the man, this becomes 'the man's sister is my (Sonia's) mother.'
Since the man's sister is Sonia's mother, the man is Sonia's maternal uncle.
Conversely, Sonia is the niece of that man.
Note: The textbook answer key has a typographical error marking this as Option C (Wife). The logically correct choice is Option D (Niece).
Hence, **Option D** is the correct answer.
