How many male members are there in the family?

Solution

From the statements:
• C is wife of B ⇒ B is male, C is female.
• D is grandmother/mother ⇒ D is female.
• F is granddaughter ⇒ F is female.

So far, confirmed genders:
Male: B
Female: C, D, F

The problem says there are two married couples.
One couple is clearly (B, C).
The second couple could be:
• (D, E) ⇒ E male, or
• (A, E) ⇒ A male, or
• (A, someone) depending on relations not specified.

Since the gender of A and E is not fixed by the data, the total number of male members can vary.

Therefore, the exact number of male members cannot be uniquely determined.

Correct conclusion: Cannot be determined
