Blood Relation Problem

Answer: (A) Brother

Explanation:

Let's break down the statement made by the girl:
"He is the son of the daughter of the father of my uncle."

1. "My uncle": This refers to the girl's uncle.
2. "Father of my uncle": This is the girl's grandfather (either paternal or maternal).
3. "Daughter of the father of my uncle": This daughter of the girl's grandfather could be either the girl's mother or her aunt.
4. "Son of the daughter of the father of my uncle":
   • If the "daughter" is the girl's mother, then the boy is the son of the girl's mother, making him the girl's brother.
   • If the "daughter" is the girl's aunt, then the boy is the son of the girl's aunt, making him the girl's cousin.

However, in blood relation problems, when a simpler and direct relationship exists, it is usually the intended answer.
In this case, Brother is a more direct relation than Cousin when the phrasing allows for both interpretations.

The most direct interpretation of "daughter of the father of my uncle" leading to the boy being a brother
is when that daughter is the speaker's mother. Therefore, the boy is the girl's brother.
