Solution

The correct option is B
A is correct and R is incorrect

Digestion of cellulose takes more time because the enzymes required for cellulose digestion are produced by the ruminant bacteria. These bacteria live in the gut of the herbivores and take time to completely breakdown the cellulose. Since, cellulose digestion takes time so the herbivores have a longer small intestine which ensures that the food stays in the intestine for a longer period of time for complete digestion.
