A Correct answer
Explanation

Organic manure is a natural fertilizer derived from animal wastes or plant residues and is generally beneficial for soil health rather than a cause of serious pollution. In contrast, vehicular exhaust, chemical fertilizers, and plastic garbage are major contributors to air, water, and land pollution. Organic farming practices actually help reduce environmental degradation.
