Your answer: —  Â·  Correct: A
Explanation

Organic farming emphasizes crop rotation, green manure and biological pest control to maintain soil health, release nutrients naturally, and produce food in an eco-friendly, pollution-free environment, preserving regenerative capacity of soil [1]. Shifting (jhum) or slash-and-burn cultivation involves clearing and burning forests, leading to depletion of forest, water and soil resources and reduced fertility, making it environmentally harmful [2]. Cultivation of high-yielding varieties often demands increased chemical fertilizers and pesticides, which can degrade soil health and ecology [3]. Protected cultivation in poly/greenhouses controls growth factors and can increase income, but relies on high-tech inputs and energy for climate control rather than being inherently low-impact [4]. Hence organic farming is the most eco-friendly choice.
