Show answer and explanation

Correct answer: (c) Organic fertilizers, recycled farm wastes and bio-agents are used in maximum quantities

In organic farming, chemical fertilisers and pesticides are avoided or used as little as possible.

Instead, organic manures, compost, recycled farm wastes and bio-agents (such as biofertilisers like blue-green algae) are used as much as possible.
