Question

Assertion (A) : Sustainable agriculture is environment friendly.
Reason (R) : It prevents use of chemical fertilizers to protect soil.
(A) Both (A) and (R) are correct and (R) is the correct explanation of (A).
(B) Both (A) and (R) are correct but (R) is not the correct explanation of (A).
(C) (A) is correct but (R) is not correct.
(D) (A) is not correct but (R) is correct.

Accepted Answer

## Model Answer **(C) (A) is correct but (R) is not correct.** Sustainable agriculture is indeed environment friendly, but it does not **prevent** use of chemical fertilizers — it involves **avoiding/preventing adverse effects** to soil, water and biodiversity by reducing chemical use, not an absolute prevention. ## Explanation The Assertion is correct — sustainable agriculture uses environment friendly farming methods without damaging natural systems. However, the Reason is worded incorrectly; the textbook states sustainable agriculture "involves preventing the use of chemicals so as to **avoid adverse effects** to soil, water and biodiversity" — it aims to minimise harmful impacts, and the reason's phrasing ("prevents use of chemical fertilizers to protect soil") is an oversimplification/inaccuracy. Hence (R) as stated is not fully correct, making option **(C)** the right answer.
