Detailed Solution & Explanation

1. The question asks how B is related to C. We are given that D is the brother of B. 2. Statement I: "The son of D is the grandson of C." Since D is male, his son is C's grandson, which implies D is the son of C. Since D is B's brother, B is also C's child. However, this does not tell us the gender of B, so B could be the son or daughter of C. 3. Statement II: "B is the sister of D." This establishes that B is female. 4. Combining both statements: Statement I tells us B is the child of C, and Statement II tells us B is female. Together, they establish that B is the daughter of C. Thus, both statements I and II are necessary. Hence, **Option D** is the correct answer.
