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