P is the brother of Q and R. S is mother of R, and T is father of P. Which of the following statements is not exactly true?

Explanation

Let's analyze the given relationships:

  • P is the brother of Q and R.
  • S is the mother of R.
  • T is the father of P.

From this, we can deduce:

  • T is also the father of Q (since P and Q are siblings).
  • P is also the son of S (since S is R's mother and P and R are siblings).
  • S is also the mother of P (as explained above).

Therefore, all the statements except (D) Q is T's son are true.
