Mammals with a carnivorous diet include the

a. rabbit, mouse, elephant, zebra, and monkey.

b. bear, badger, fox, human, and rat.

c. aardvark, whale, hyena, dog, dolphin, and mole.

d. giraffe, deer, elk, walrus, human, and rat

I want to say C. Aardvark, whale, hyena, dog, dolphin, and mole.

All of these mammals eat primarily meat.

B. is a close second, but the human and rat are both omnivores and don't regularly rely on meat for most of their dietary needs.
