Quick Solution

The best way to solve this blood relation puzzle is to draw a family tree based on the clues to determine the relationship between C and A.

1. Building the Family Tree

• "C is wife of B and mother of F" tells us B and C are a married couple, and F is their child.
• "D is mother of B" makes D the mother of B.
• "F is the grand daughter of E" means E must be the other grandparent. Since D is B's mother, E must be B's father.
• "D is grandmother of A" means A must also be a child of B and C, which makes A and F siblings.

This gives us the following family structure:

2. Determining the Relationship

- The question asks for the relationship of C to A (What is C to A?).
- Looking at the family tree, B and C are the parents in Generation 2.
- A and F are their children in Generation 3.
- Therefore, C is the mother of A.

Final Answer: C is A's Mother.
