- Deepak is Ravi's brother, so Deepak is also Rekha's child.
- Deepak is Rekha's son.
Answer: Son.
The idea
A sibling relation transfers parenthood: whoever is the parent of one brother is the parent of the other.
Shortcut. Ravi's brother shares Ravi's mother, so Deepak is Rekha's son at once; Atul plays no part in this question.
Common trap. "Nephew" — pulling Atul into the chain: Deepak is Atul's nephew, but the question asks about Rekha, who is his mother.
