The Correct Option is C

Solution and Explanation


Concept: This problem is based on logical family relationships and gender deduction step-by-step. Step 1:Analyze relation between B and C.
  • B is the son of C
  • C is not the mother → C is the father
So, C is male.
Step 2:Relation between A and C.
  • A and C are married
  • Since C is male → A is female

Step 3:Relation of D.
  • D is daughter of A → D is female

Step 4:Relation of E.
  • E is brother of C → E is male

Step 5:Relation of F.
  • F is brother of B → F is male

Step 6:Identify genders of all members.
  • A → Female
  • B → Male
  • C → Male
  • D → Female
  • E → Male
  • F → Male

Step 7:Count total males.
Males are: \[ B, C, E, F \] So total males = 4.
Final Answer: 4
