I have been asked this question in semester exam.

I'm obligated to ask this question of Comparison of Aerobic and Anaerobic Solid Waste Treatment in section Biotechnology for Solid Waste Management of Environmental Biotechnology

Answer 1

The correct answer is (d) Post-treatment

Easiest explanation: Post-treatment is usually not done in aerobic digestion whereas, in anaerobic digestion Post-treatment is most necessary and is done for about 2-8 weeks, but low degradation rate, high odor emission, narrow suitability of wastes, these are some of the characteristic of aerobic digestion including sanitation, costs etc.
