Data Sufficiency — Relationships: How is J related to P? Statement I: M is brother of P and T is sister of P. Statement II: P's mother is married to J's husband, who has one son and two daughters. Decide which statements are sufficient to answer the question. Choose the correct sufficiency option.

Difficulty: Medium

Correct Answer: Statement II alone is sufficient, but Statement I alone is not sufficient.

Explanation:


Statement I
Gives P's siblings but says nothing about J ⇒ insufficient.


Statement II
"P's mother is married to J's husband" ⇒ J's husband and P's father are the same person. Under standard monogamy assumption in family puzzles, this implies J is P's mother.
Extra clause "who has one son and two daughters" is consistent with P's sibling set but not required for identifying J's relation.


Final Answer
Statement II alone is sufficient, but Statement I alone is not sufficient.
