Correct Answer & Explanation
Option D
Let's analyze each option:
• We need to find P as the sister of S. This means P must be female and P and S must share parents or at least one common parent, with P being in the same generation as S.
Let's check option D: P ÷ Q + R × S
• P ÷ Q: P is the daughter of Q (P is female).
• Q + R: Q is the father of R.
• R × S: R is the brother of S.
From these, we have:
• P is Q's daughter.
• Q is R's father.
• R is S's brother.
This implies Q is the father of P and R. Since R is S's brother, Q is also S's father. Thus, P, R, and S are siblings, and P is female. Therefore, P is the sister of S.
