Best answer
Correct choice is (a) Aerobic decomposition

The best I can explain: Aerobic decomposition (fermentation) process produces carbon dioxide, ammonia and other small amounts of gases, heat in large quantities and a final product that can be used as a fertilizer. Aerobic decomposition is process of decomposition in presence of oxygen.
