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:

Generation 1: E (Grandfather) <=> D (Grandmother)
             |
Generation 2:        B (Father) <=> C (Mother)
                  |___________
                  |           |
Generation 3:                F         A

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.
