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 analyze the relationships step-by-step to construct the family tree of 8 members (4 males and 4 females):

1. Generations and Core Family Structure:
- "W is the maternal grandmother of K" implies W is a female in the first (top) generation.
- "K is the male child of C" and "C is the son-in-law of H". Since W is K's maternal grandmother, H must be W's husband (male) in the first generation.
- C is a male (son-in-law) married to one of H and W's daughters. K is their son (male child).

2. Siblings and In-Laws:
- "H is the father-in-law of B" and "D is the sister-in-law of B".
- Since H and W have daughters, one daughter is married to C (mother of K), and another child B (male) is married to D's sibling, or D and B are related via marriage.
- "S is the sibling of D". D is female ("sister-in-law"). S is female to maintain the equal ratio of 4 males and 4 females.
- Specifically, the daughters of H and W are D (female), S (female, married to C), and B is a male married to D's sister, or B is married into the family.
- Let us check the gender balance: Males = {H, C, B, K} (total 4 males). Females = {W, D, S, G} (total 4 females).

3. Determining G's Relation to D:
- "G is the child of B". Since G is female (to have 4 females: W, D, S/mother of K, G), G is the daughter of B.
- B is married to a sibling of D, making D the aunt of G.
- Therefore, G is the Niece of D.
