• A. T is Q’s father.
• B. S is P’s mother.
• C. P is S’s son.
• D. Q is T’s son.

Hint:

Draw a family tree to clarify relationships. Avoid assuming genders unless explicitly stated.

Answer 1

The Correct Option is D

Given: - P, Q, and R are siblings. P is the brother of Q and R. - S is the mother of R, and by extension, the mother of P and Q. - T is the father of P, and therefore likely the father of his siblings. Evaluating the options: - (a) True: T is Q’s father, as he is the father of the siblings. - (b) True: S is P’s mother. - (c) True: P is S’s son. - (d) Cannot be definitely true: Q’s gender is not specified. Q could be a daughter, making the designation of "son" an assumption.
