Correct option is B
Concept:
This type of question involves understanding family relationships. We are given a statement and need to deduce the relationship between two people based on the provided information.
Statement Breakdown:
Pradeep says, “Vishal's mother is the only daughter of my mother.”
To break it down:
· "The only daughter of my mother" means Pradeep is talking about his sister because she is the only daughter of Pradeep's mother.
· The phrase “Vishal's mother” means the person Pradeep is referring to as his sister is Vishal's mother.
Solution:

If Vishal's mother is Pradeep's sister, it implies that Pradeep is the brother of Vishal's mother. In other words, Pradeep is Vishal's maternal uncle (the brother of one's mother is referred to as a maternal uncle).
Correct Answer:
(b) Maternal uncle.
