The correct option is Grand father.

Let us analyze the relationships step-by-step from the given information:

1. T is father-in-law of P who is mother of S:
P is the mother of S. Since T is the father-in-law of P, T is the father of P's husband.

2. Q is sister of S but daughter of U’s wife:
Since Q is the sister of S, both Q and S share the same parents. P is the mother of S and Q. Since Q is the daughter of U's wife, P must be U's wife, which means U is the husband of P and father of S and Q.

3. Connecting T to S:
From step 1, T is the father of P's husband. From step 2, P's husband is U. Therefore, T is the father of U.
Since U is the father of S, and T is the father of U, T is the father of S's father.

Thus, T is the Grand father (paternal grandfather) of S.
