Show the answer and explanation
Correct answer: C
Explanation
Kunal is older than exactly two people, so he is 3rd oldest, with two above him and two below.
Manoj > Irfan > Jasleen is a chain of three; it cannot fit entirely below Kunal (only two places), so Manoj is above Kunal and Irfan, Jasleen are below.
Harini > Manoj, so the order is Harini > Manoj > Kunal > Irfan > Jasleen.
Below Manoj: Kunal, Irfan and Jasleen, which is 3 people.
Worth noting
2 counts only the chain Manoj > Irfan > Jasleen and forgets that Kunal is also younger than Manoj.
