Chanda is the wife of Bharat, and Mohan is the son of Chanda. Ashish is the brother of Bharat and the father of Dhruv. How is Mohan related to Dhruv?

Introduction / Context:
This question describes two brothers, Bharat and Ashish, and their respective children, Mohan and Dhruv. You must determine how Mohan is related to Dhruv. The scenario is a classic example of a cousin relationship: children of two brothers (or of two sisters, or of a brother and a sister) are cousins.

Given Data / Assumptions:
- Chanda is the wife of Bharat. - Mohan is the son of Chanda (and therefore of Bharat). - Ashish is the brother of Bharat. - Dhruv is the son of Ashish. - All relationships are standard; there is no adoption or remarriage mentioned.

Concept / Approach:
The main idea is that Bharat and Ashish are brothers, so they are siblings in the same generation. Their children form the next generation. Children of siblings are cousins. Hence, Mohan (Bharat's son) and Dhruv (Ashish's son) are cousins. Since the question specifically asks how Mohan is related to Dhruv, we answer that Mohan is Dhruv's cousin.

Step-by-Step Solution:
Step 1: Recognise that Bharat and Ashish are brothers, which puts them in the same generation and with the same parents. Step 2: Chanda is married to Bharat, and their child is Mohan. So Mohan is Bharat's son. Step 3: Dhruv is the son of Ashish, the brother of Bharat. Step 4: Mohan is the child of Bharat, and Dhruv is the child of Ashish. Because Bharat and Ashish are brothers, Mohan and Dhruv are children of two siblings. Step 5: Children of siblings are cousins. Therefore, Mohan is Dhruv's cousin.

Verification / Alternative check:
Draw a family tree: place Bharat and Ashish as two brothers on one level. Below Bharat and his wife Chanda, place Mohan. Below Ashish, place Dhruv. From Mohan's viewpoint, Dhruv is the son of his father's brother. That is exactly the definition of a cousin. The direction is symmetric: from Dhruv's point of view, Mohan is also his cousin. No other close relation fits this exact structure.

Why Other Options Are Wrong:
- Sister: Mohan is male and is from a different nuclear family, so he cannot be Dhruv's sister. - Brother: A brother shares parents with you; Mohan and Dhruv have different fathers. - Mother: Mohan is not only of a different gender but also of a younger generation relative to Bharat and Ashish, so he cannot be Dhruv's mother. - Uncle: An uncle is a sibling of a parent or the spouse of an aunt, a generation above. Mohan is in the same generation as Dhruv, not above him.

Common Pitfalls:
Sometimes candidates overlook the phrase Ashish is the brother of Bharat and focus only on the children, leading to incorrect ideas such as Mohan being a brother to Dhruv. Another common error is to misinterpret wife of Bharat and father of Dhruv as implying a more complex relationship. Always remember that once two adults are identified as siblings, their children are cousins unless stated otherwise.

Final Answer:
Mohan is related to Dhruv as his cousin.
