Detailed Solution & Explanation

Let's decode the statement step-by-step:
1. 'brother of my wife': The man's wife's brother.
2. 'The son of her only brother is the brother of my wife': This means the son of the lady's only brother is the brother of the man's wife.
3. Since the lady's brother's son is the man's wife's brother, the lady's brother must be the father of the man's wife.
4. The father of the man's wife is the man's father-in-law. Therefore, the lady's brother is the man's father-in-law.
5. Since the lady is the sister of the lady's brother (the man's father-in-law), the lady is the sister of the man's father-in-law.
Note: The textbook answer key has a typographical error marking this as Option B (Grandmother). The correct option is Option C (Sister of father-in-law).
Hence, **Option C** is the correct answer.
