Study the following details carefully and answer the question that follows:

There are eight members in a family with an equal number of males and females. W is the maternal grandmother of K. C is the son-in-law of H. K is the male child of C. S is the sibling of D. D is the sister-in-law of B. H is the father-in-law of B. G is the child of B.

How is G related to D?

The correct option is Niece.

Let us break down the family relations step-by-step based on the given information:

1. Total Members and Gender Distribution:
There are 8 family members in total, with an equal number of males and females (4 males and 4 females).

2. Generations and Parent-Child Relationships:
- "W is the maternal grandmother of K": W is female (Generation 1). K belongs to Generation 3.
- "K is the male child of C": K is male. C is K's parent (Generation 2). Since W is the maternal grandmother, C must be married to W's daughter, or C is W's daughter.
- "C is the son-in-law of H": C is male, which means C is married to a daughter of H. Since W is the maternal grandmother of K, H and W are married (Generation 1), where H is male (father-in-law of C) and W is female.
- So, Generation 1 consists of H (Male) married to W (Female).

3. Children of H and W (Generation 2):
- C (Male) is married to one of the daughters of H and W.
- "H is the father-in-law of B": B is married to one of H's children.
- "D is the sister-in-law of B" and "S is the sibling of D": This indicates D, S, and the spouse of B are siblings (children of H and W).
- Since C is the son-in-law of H, C must be married to B (who is a female child of H and W), making D the sister-in-law of B.
- Thus, the children of H (Male) and W (Female) in Generation 2 are B (Female, married to C), D (Female), and S (Male to balance the gender count).

4. Grandchildren (Generation 3):
- "G is the child of B": Since B and C are married, G and K are the children of B and C.
- K is a male child.
- Let's check the total gender count:
- Males: H, C, S, K (4 males)
- Females: W, B, D (3 females so far)
- To maintain an equal number of 4 males and 4 females, G must be female.

5. Relation between G and D:
- D is the sister of B (G's mother).
- Since G is a female child of B, G is the niece of D.

Therefore, G is the Niece of D.
