Correct answer: B
CONCEPT
In a family-counting question, classify every listed person exactly once under the category requested by the stem.
Marriage changes family relationships, but it does not change whether a listed person belongs to the male or female group.
APPLICATION
Count the male members: 1 husband + 2 sons = 3.
Count the female members: 1 wife + 3 daughters + 2 sons’ wives = 6.
CROSS-CHECK
The two groups contain 3 + 6 = 9 people. This matches the stated total: 2 parents + 3 daughters + 2 sons + 2 daughters-in-law = 9. Therefore, the family has 3 males and 6 females, respectively.
