In a family of two males and three females, A is the daughter of B and sister of C. E is the spouse of B and mother of D. C is not the brother of D. Which of the following statements is NOT correct?

Correct option is B

Given:

• There are two males and three females in the family.
• A is the daughter of B and the sister of C.
• E is the spouse of B and the mother of D.
• C is not the brother of D.

Family Tree Analysis:

1. B and E are a married couple:

   • B is male (father).
   • E is female (mother).

2. Children of B and E:

   • A: Daughter of B and E.
   • C: Sibling of A and D. Since C is not the brother of D, C must be female (sister).
   • D: Another child of B and E. The gender of D is not specified directly.

3. Gender breakdown:

   • There are two males in the family.
     • B (father) is one male.
     • Therefore, D must be male to satisfy the condition of having two males.

Verification of Statements:

1. Statement (a): E is the mother of A.

   • This is correct, as E is explicitly stated as the mother of A.

2. Statement (b): D is the sister of C.

   • This is incorrect because D is male (to satisfy the condition of two males in the family).

3. Statement (c): C is the daughter of B.

   • This is correct, as C is explicitly stated as the sister of A and D, making her the daughter of B.

4. Statement (d): A is the sister of D.

   • This is correct, as A is explicitly stated as the sister of D.

Final Answer:

The NOT correct statement is (b) D is the sister of C.
