The correct option is D Neelesh
At first, we arrange the given information in the descending order of age.
1. Mohan is older than Raju but not as old as Lalit, i.e., Lalit > Mohan > Raju ...(i)
2. Lalit is older than Neelesh and Kabir, i.e., Lalit > Neelesh and Kabir ...(ii)
3. Neelesh is younger than Raju but is not the youngest, i.e., Raju > Neelesh ...(iii)
From Eqs. (i), (ii) and (iii), we can write the order: Lalit > Mohan > Raju > Neelesh > Kabir
Hence, Neelesh is the fourth in the descending order.
