Pointing to a boy, a woman said, “He is the son of my father’s only daughter .” How is the boy related to the woman?

Correct Answer: Son

To determine how the boy is related to the woman, let us break down the statement made by the woman step-by-step:

Step 1: Analyze "my father’s only daughter"
The woman is speaking, so "my father" refers to the woman's father.
The phrase "my father’s only daughter" means the only female child of her father. Since the speaker is a woman herself, she is referring to herself.

Step 2: Substitute back into the full statement
Now substitute "myself" into the original statement:
“He is the son of [myself].”
This simplifies directly to: “He is my son.”

Therefore, the boy is the Son of the woman.
