Answer
Correct Answer: Neither I nor II is sufficient
Explanation
Assessment
- Statement I: H is the only daughter of M's wife (X). This implies M has exactly one daughter, but he may have zero, one, or more sons. The total number of children is unknown.
- Statement II: Tells about M's siblings (K and J), not M's children. Irrelevant to the question.
Combined Even together, we only know there is one daughter; the count of sons (if any) is undetermined.
Final Sufficiency Choice Neither I nor II is sufficient.
