Pointing to a man,a woman said,"His mother is the only daughter of my mother."How is the woman related to the man?

Options

A. Mother
B. Daughter
C. Sister
D. Grand father

Explanation

To solve the problem step by step, we can break down the statement made by the woman and analyze it:

1. **Understanding the Statement**: The woman says, "His mother is the only daughter of my mother." Here, "his mother" refers to the mother of the man she is pointing to.

2. **Identifying "My Mother"**: The phrase "my mother" refers to the woman's own mother.

3. **Finding the Only Daughter**: The statement mentions that "the only daughter of my mother" is significant. If the woman's mother has only one daughter, that daughter must be the woman herself.

4. **Connecting the Dots**: Since the only daughter of the woman's mother is the woman herself, we can conclude that the woman is saying that "his mother" (the mother of the man) is actually herself.

5. **Conclusion**: Therefore, the woman is the mother of the man.

So, the relationship between the woman and the man is that the woman is the man's mother.

### Final Answer:
The woman is the mother of the man.
