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.

What is the total number of generations in this family?

The correct answer is 3.

Let us analyze the given information step-by-step to establish the family relationships, gender of each member, and determine the total number of generations.

Step 1: Given Information Breakdown
- Total members = 8 (4 males and 4 females).
- W is the maternal grandmother of K. (This means W is female, and there are 3 generations present: W in Generation 1, K's parent in Generation 2, and K in Generation 3).
- K is the male child of C. (K is male. Since W is K's maternal grandmother, C must be married to W's daughter).
- C is the son-in-law of H. (C is male. H must be married to W, making H male and the maternal grandfather of K).
- So, Generation 1 consists of H (male) and W (female).
- Generation 3 contains K (male).

Step 2: Analyzing Generation 2 and siblings
- H and W have children in Generation 2. C (male) is married to one of W's daughters.
- H is the father-in-law of B. This means B is married to a child of H and W.
- D is the sister-in-law of B. (D is female).
- S is the sibling of D.
- G is the child of B. (G belongs to Generation 3).

Step 3: Determining Generations and Members
- Generation 1 (Oldest generation): H (Father/Grandfather, Male) and W (Mother/Grandmother, Female).
- Generation 2 (Middle generation): Children of H & W and their spouses (C, B, D, S).
- Generation 3 (Youngest generation): Grandchildren (K, G).

Conclusion:
The family members span across 3 distinct generations:
1. First Generation: H and W
2. Second Generation: C, B, D, and S
3. Third Generation: K and G

Therefore, the total number of generations in this family is 3.
