The correct answer is (b) Low odor emission

To explain I would say: Low degradation rate, high odor emission, narrow suitability of waste, Gas phase, these are the characteristic of aerobic digestion whereas in anaerobic digestion, the degradation rate is comparatively high, odor emission is low, it doesn’t have Gas phase, only solid and liquid phase and wide suitability of wastes.
