Correct choice is (d) Open vessel

For explanation I would say: The anaerobic digestion of solid wastes is usually carried out under anaerobic conditions where the temperature is controlled and mainly high moisture control. This is usually carried out in a closed vessel to maintain temperature and particular conditions inside the vessel. Therefore, this digestion cannot be carried out in an open vessel.
