A is the daughter-in-law of C. B is the son of G. D is the brother-in-law of E. E is the grandmother of F. F is the only son of B. E has no siblings. H is the child of C and is not married. F is married. B has two children. There is no single parent in the family.

How is C related to E?

The correct option is Daughter-in-law.

Let us break down the relationships step-by-step to determine how C is related to E:

1. Analyze the generation of B, E, and F:

• E is the grandmother of F.
• F is the only son of B.
• B has two children, and F is married.
• Since E is the grandmother of F and B is the parent of F, E must be the mother of B (or B's spouse). Let us place E in the topmost generation given in these statements.

2. Analyze B, G, and E's generation:

• B is the son of G.
• Since B is the child of G, and E is the grandmother of F (who is B's child), G and E form a married couple (Generation 1). Given B is their son, G and E are the parents of B.

3. Analyze D, E, and the married couples:

• D is the brother-in-law of E. But wait! The problem states "E has no siblings." Therefore, D must be the brother of E's spouse (G).

4. Connect C, H, A, and B:

• "There is no single parent in the family." This means every parent in the family tree must have a spouse.
• B has two children (one is F). B is married.
• A is the daughter-in-law of C. For A to be the daughter-in-law of C, C must be the parent of A's husband (or spouse).
• Since B is married and in Generation 2 (child of G and E), B's spouse is A, which makes C the mother/parent-in-law or parent of B's spouse, OR C is married to B. However, let's look at C and H: "H is the child of C and is not married."
• Since B has two children, and F is one of them, H must be the second child of B and B's spouse! This makes C the spouse of B (or the wife of B).
• If C is the wife of B (the mother of F and H), then A is the daughter-in-law of C (wife of F, since F is married and is the son of B and C). This fits all conditions perfectly!

5. Determine the relationship between C and E:

• E is the mother of B.
• C is the wife of B.
• Therefore, C is the daughter-in-law of E.
