The dental formula of the rabbit is 2 x (I 2/1 C 0/0 PM 3/2 M 3/3). The total number of teeth is therefore 28. There are no canines present. The gap between the incisors and premolars is known as the diastema. The premolars and molars are often grouped together and called the cheek teeth. The incisors are used to slice the food and the cheek teeth grind the food.

Canines, the tearing teeth are well-developed in carnivores and ill-developed or absent in herbivores.

Now answer the following:
(i) In frogs, all the teeth in the upper jaw look-alike, whereas in human beings they are different. The type of dentition in human beings can be called .........
(a) Homodont (b) Isodont (c) Heterodont (d) Acrodont
