How many daughters does D have ?

Statement (I) : B and F are sisters of A.

Statement (II) : C is the brother of A and F

Statement (III) : C and E are sons of D.

Choose the correct option to decide whether the data provided in the statements are sufficient to answer the question:

All the statements together are not sufficient

The correct answer is Option (4) → All the statements together are not sufficient.

From all the statements, we can determine that B and F are daughters of D, but we cannot determine whether A is male or female. Therefore, without knowing A's gender, we cannot find the correct answer.

Hence, all the statements together are not sufficient to find the correct answer.
