Concept:Use family-tree relations to trace parentage through sibling, wife, and nephew links.
Explanation:Priya is Qureshi's sister, so Qureshi is male.
Seema is Qureshi's wife and Wasim's daughter-in-law, so Wasim is Qureshi's father.
Wasim has only two children, hence his children are Qureshi and Priya.
Mohit is Wasim's grandson and Priya's nephew.
Since Priya is Qureshi's sister, Mohit must be Qureshi's son.
Mohit is the brother of Vineet, so Vineet is also Qureshi's child.
Vineet is male, so Vineet is Qureshi's son.
Answer:Vineet is Qureshi's son.
