- A. Q is a sister of S
- B. Q is a daughter of S
- C. Q is the mother of S
- D. Q is a sister of the husband of S (Correct answer)
Correct Answer
Option D — Q is a sister of the husband of S
Detailed Solution & Explanation
The correct answer is Option D.
Key Points
- Q and R are children of P; S is R's spouse and the mother of T.
- So R is S's husband, and Q (being R's sibling) is therefore the sister of S's husband.
Additional Information
- P has a son and a daughter, so among Q and R one is the son (R, married to S) and the other the daughter (Q). Q is thus "a sister of the husband of S" → Option D.
