Official UPSC Answer KeyUPSC Prelims 2016 • International Relations and Current Affairs

Correct Answer: Option (B) — Neem coating slows down the rate of dissolution of urea in the soil

Concept & Option Breakdown

Standard Reference Verified

Neem oil acts as a natural nitrification inhibitor. When urea is coated with neem, it retards the hydrolysis and nitrification process, slowing down the dissolution rate of urea. This improves nitrogen use efficiency, reduces leaching losses, and curbs diversion of subsidized agricultural urea to industrial units.

Elimination Heuristic & Exam Approach

Option (c) uses an extreme impossibility ('not at all released'), making it instantly eliminable.
