A and B are children of D.
From (1), C is the brother B and son of E.
Since, the sex of D and E are not known. Hence (1) is not sufficient to answer the question.
From (2). F is the mother of B. Hence, F is also the mother of A. Hence D is the father of A.
Thus, (2) is sufficient to answer the question.

To determine the father of A, we need to know the parentage of A.

- Statement (1) tells us that A and C are siblings and that they have the same father, D.

- Statement (2) tells us about the mother of B, but does not provide any information about the father of A.

Therefore, statement (1) is necessary to answer the question, while statement (2) is not relevant. Hence, the correct answer is option 'B'.
