Best answer
Correct answer is (a) Aerobic composting

For explanation I would say: Aerobic composting is used to treat dry solid wastes which can thereby produce compost which can be readily marketed, vermicomposting is usually used to treat lignocellulosic waste, anaerobic composting and Anaerobic digestion are the same thing which is used to treat simple organic wastes, hence, Aerobic composting. Is most suitable for dry solid wastes.
