Detailed Solution & Explanation
We are given the following relationships:
1. C is the mother of A and B.
This implies that C is female.
It also establishes a direct parent-child relationship: C is the parent of B. 2. D is the husband of B.
This implies that D is male.
It also implies that B is female (since D is her husband).
This establishes a marital relationship: D is married to B. Now, we need to determine the relationship of C to D.
From statement 1, we know that C is the mother of B.
From statement 2, we know that B is the wife of D. Combining these two facts:
C is the mother of B, and B is the wife of D.
Therefore, C is the mother of D's wife. In family terminology, the mother of one's spouse is referred to as the Mother-in-law.
Thus, C is the Mother-in-law of D. Let's evaluate the given options:
(A) Mother: C is not D's biological mother.
(B) Aunt: An aunt is the sister of one's parent. C is B's mother, not D's aunt.
(C) Mother-in-law: This aligns perfectly with our derivation, as C is the mother of D's wife (B).
(D) Sister: C is not D's sister. Based on the rigorous derivation, the relationship of C to D is Mother-in-law. It appears there is a typographical error in the provided answer key, which states **Option B** (Aunt) as correct. Mathematically and logically, **Option C** (Mother-in-law) is the correct relationship derived from the given statements. Therefore, the correct choice is **Option C**.
This implies that C is female.
It also establishes a direct parent-child relationship: C is the parent of B. 2. D is the husband of B.
This implies that D is male.
It also implies that B is female (since D is her husband).
This establishes a marital relationship: D is married to B. Now, we need to determine the relationship of C to D.
From statement 1, we know that C is the mother of B.
From statement 2, we know that B is the wife of D. Combining these two facts:
C is the mother of B, and B is the wife of D.
Therefore, C is the mother of D's wife. In family terminology, the mother of one's spouse is referred to as the Mother-in-law.
Thus, C is the Mother-in-law of D. Let's evaluate the given options:
(A) Mother: C is not D's biological mother.
(B) Aunt: An aunt is the sister of one's parent. C is B's mother, not D's aunt.

Mathematically and logically, **Option C** (Mother-in-law) is the correct relationship derived from the given statements. Therefore, the correct choice is **Option C**.
