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

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).

Correct Mr. Sunder, but no where in the given statement is mentioned that B has to be sister. So if we consider the only A point, then D and B becomes brother. The confusion is related to the sex of B. Hence if you consider B as male A is correct and if you consider B as female then D is correct.

@All
You all are wrong. The given answer is correct.
From I: D is MALE, B is MALE or FEMALE. So, we can find only that 'B is SON or DAUGHTER of C'. There is no info to find whether B is male/female in I.
From II: We can find that D is MALE or FEMALE, B is FEMALE.
From I & II: We can find that B is the daughter of C.
Please be careful on solving these kind of questions.
Hope this info may help you a little bit. Have a nice day!

Ya ya I too agree with Mr. Sundar. We must find relation between B and C.
So, the second statement also required to solve this problem.

The given answer is correct. Because we have to know how B is related to C?
And for answering this we need to know that B is male or female.
Because after getting that B is the sister of D we will sure that B is the daughter of C. Without 2nd statement it can be B is the daughter of C as well as son of C.

The son of D is the grandson of C.
So, D may be son in law of C.
In this case, B is not the daughter of C.
Please reply my query.
