Answer 1

The Correct Option is C

Let's decode the relationship in the expression: - "Q + R" means Q is the sister of R. - "R - P" means R is the father of P. - "P \times N" means P is the brother of N. - "N - S" means N is the father of S. From these relationships, we know that R is the father of P, and P is the brother of N. Therefore, R is the uncle of S.
Thus, the correct answer is (C) Uncle.
