Read the question & statements (I & II). Decide whether the data provides in the statement are sufficient to answer the question.
Answer & explanation
Correct answer: option 3
Statements : I. X's father has three children.
II. Y is X's brother and son of W.

So none of the statement is able to tell that how many son's does W have .
