Why is organic farming preferred over the heavy use of chemical fertilisers and pesticides?
AIt can instantly double the crop yield in one season
BIt avoids poisonous chemicals and helps maintain natural balance
CIt removes the need for any farm soil at all to grow
DIt lets crops grow fully without any sunlight
Answer & Solution
Correct answer: B. It avoids poisonous chemicals and helps maintain natural balance
1. Chemical fertilisers and pesticides reach the body through food and water and harm health and environment.
2. Organic farming bans these chemicals and uses local sturdy varieties, maintaining natural balance.
3. It does not promise instant doubling of yield, and crops still need soil and sunlight, so those options are false.
4. The soil-free option confuses organic farming with hydroponics, which is a separate technique and a trap here.
