A
cat
B
man
C
tiger
D
rabbit
Explanation: 

Detailed explanation-1: -Rabbits have incisor and cheek teeth. The cheek teeth include both premolars and molars. Rabbits do not have canine teeth as in cats, dogs, ferrets and hedgehogs.

Detailed explanation-2: -Rabbits do not have canine teeth. Rabbit teeth are hypsodontic – this means that they continue to grow throughout the rabbit’s life.

Detailed explanation-3: -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.

Detailed explanation-4: -Rodents lack canines. The tusks of wild boar, walrus, and the extinct sabre-toothed cat are enlarged canines. (The tusks of elephants are upper incisors, not canine teeth. Canine teeth are absent.)

Detailed explanation-5: -The correct option is C Canines.
