Why can't D be the C's Son and B be the daughter-in-law?

Using statement 1, we can infer the relationship between D and C; then, why do we need to determine B's gender?

Given: D is the brother of B.
We need to know B's relation to C.
Statement 1: The son of D is the grandson of C.
This tells us that D's son is C's grandson, so D is likely C's child. Since B is D's sibling, B is also C's child.
Statement 1 is sufficient.
Statement 2:.B is the sister of D.
This only tells us that B is female and D is her brother. It gives no information about C.
Statement 2 is not sufficient.
Answer:
Only 1 (A).
