Difficulty: Medium
Correct Answer: None of these
Explanation:
Decode step by step P % Q ⇒ P is mother of Q. Q + R ⇒ Q is father of R. R - T ⇒ R is brother of T (so R and T share parents). T x K ⇒ T is daughter of K (so K is parent of T and R).
Inference Parents of R and T are Q (father) and K (mother). P is mother of Q ⇒ P is K's mother-in-law.
Conclusion Since “mother-in-law” is not among the given options, the correct choice is None of these.
