Organic farming may be defined as a farming system with no or minimal use of chemicals as fertilizers, herbicides, pesticides etc, and with the maximum use of organic manures, recycled farm waste, use of bio-agents (such as culture of blue green alagae) in preparation of biofertilizers, neem leaves or turmeric specifically in grain storage as bio-pesticides, with healthy cropping systems.

Thus, the correct answer is option A.
