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 S related to K?

The correct option is Maternal uncle.

Let us analyze the given family relations step-by-step to establish the family tree:

1. Total members: 8 members in total, with an equal number of males (4) and females (4).
2. W is the maternal grandmother of K: This means W is a female (-), and K's mother is a child of W.
3. K is the male child of C: K is a male (+). Since W is K's maternal grandmother, C must be married to W's daughter.
4. C is the son-in-law of H: C is a male (+). Since C is married to W's daughter and C is the son-in-law of H, H and W form a married couple. Since W is female (-), H is male (+).
5. H is the father-in-law of B: H and W have children. One child is married to C, and another child (or B) is married into the family. Let's look at the remaining relations.
6. D is the sister-in-law of B: D is a female (-).
7. S is the sibling of D: S and D are siblings.
8. G is the child of B: B is married to one of H and W's children or siblings.

Let's map out the generations carefully:
- Generation 1 (Grandparents): H (Male) is married to W (Female).
- Generation 2 (Parents/Aunts/Uncles): Their children are D (Female), S (Male/Female), and another daughter married to C (Male). D is the sister-in-law of B (meaning B is married to D's sibling, or D is the sister of B's spouse). Since D, S, and C's wife are siblings in Generation 2, let's count gender balance:
- Males so far: H (+), C (+), K (+).
- Females so far: W (-), D (-).
- B is married to D's sibling S, or B is married to one of the siblings. If B is female (-), then B is married to S (Male, +). That gives 4 males: H, C, K, S, and 4 females: W, D, B, and C's wife (who is D and S's sister, say B is married to S, or D is sister-in-law of B).
- Thus, the siblings in Generation 2 are: D (Female), S (Male), and C's wife (Female).
- K is the child of C and C's wife (the sister of S and D).
- Therefore, S is the brother of K's mother.

Since S is the brother of K's mother, S is the Maternal uncle of K.
