D) data insufficient

Answer 1

However 1 and 2 are sufficient to know the number of siblings.

But in statement 3 it is mentioned that P and T are daughters of X.

 B) 1,2 and 3

Comments

I think it is data insufficient because the gender of S is unknown. They haven't declared P and T are the "only" daughters of X. We can't make any judgement with the given data because no absolute idea has been given about gender of S.

Yep u are right its data insufficient as no of brothers was asked not children.

I didn't notice the mistake in the question posted before. You are right, they asked number of boys of X, not total children. That's why gender requirement came in.
