Detailed Solution & Explanation
Let us systematically analyze the given statements to deduce the relationship between C and D.
Statement 1: A is the brother of B.
This implies that A and B are siblings.
The gender of A is Male (M). The gender of B is not yet specified.
We can represent this as: A (M) ↔ B
Statement 2: B is the daughter of C.
This implies that C is a parent of B.
The gender of B is Female (F).
Since B is the daughter of C, and A is the brother of B, C must also be a parent of A.
So, C is a parent of both A and B.
We can update our representation: C ↓ (A (M) ↔ B (F))
Statement 3: D is the father of A.
This implies that D is a parent of A.
The gender of D is Male (M).
From Statement 2, we know C is a parent of A. Now we know D is *the father* of A.
Since A has two parents, and D is identified as the father (Male parent), C must be the other parent.
Therefore, C and D are the parents of A (and B).
As D is the father (Male), C must be the mother (Female).
This establishes that C and D are a married couple.
To summarize the family structure:
D (Male) is the father of A.
C (Female) is the mother of A.
Therefore, D and C are husband and wife.
A (Male) and B (Female) are their children.
The question asks: "how is C related to D?"
Based on our derivation, C is the wife of D.
Let's verify with the given options:
(A) Husband - Incorrect, C is female.
(B) Wife - Correct, C is the wife of D.
(C) Granddaughter - Incorrect, C is a parent, not a grandchild.
(D) Grandfather - Incorrect, C is female and a parent, not a grandparent.
Hence, **Option B** is the correct answer.
