Solution

The correct option is B Herbivorous
In humans, the vermiform appendix is a small, finger-sized structure, found at the end of our small caecum and located near the beginning of the large intestine. Our appendix is a developmental derivative and evolutionary vestige of the end of the much larger herbivorous caecum found in our primate ancestors. In herbivorous mammals, the caecum is essential for digestion of cellulose.
