Answer 1

Answer: (C)

Rabbit is herbivorous animal and depends on cellulose based food. It has no canines in jaw. The dental formula is 2 0 3 3 / 1 0 2 3 for incisors, canine, premolar and molars in each jaw. Thus the canines are absent. There is a gap in both the jaws at the location of canines. It is called as diastema. The total number of teeth in upper jaw are 16 and 12 teeth in lower jaw. The total number of teeth are 28.
