Answer

A

Explanation

Coprophangy is found in certain mammals (e.g. Rabbits). This is the process by which many rodents form a special kind of faeces from the contents of the caecum and these are reingested, so that the food passes through the digestive system second time. Rabbit is coprophagus in habit, eating its own faeces in order to get maximum amount of nutrient from its food. Faeces produced during night alone are eaten up which are soft and moist due to incompletely digested cellulose. Thus passing through the gut once more, the faeces are subjected once again to digestion and absorption.
