Complete Answer:
Animals are categorized in the three categories on the basis of their food habits.
1. Herbivores
2. Carnivores
3. Omnivores

1. Herbivores: Herbivores are the animals that eat only plant material and plant products as the main components of their diet. Herbivores have mutualistic gut flora which help the animal to digest the plant materials or their food.
- This flora is made up of cellulose digesting protozoans or bacteria.
- Herbivores are also called as the primary consumers.
- The herbivore animals include deer, buffalo, cow, etc.

2. Carnivores: Carnivores are the animals who eat the flesh of other animals. The word carnivore is derived from the latin word which means meat eater.
- Sometimes carnivores are also predators as first they kill another animal and then eat the flesh of the killed animal.
Example – tiger, lion, fox, etc.

3. Omnivores: Omnivores are the animals that eat both the plant materials and flesh of the animals.
- Omnivores obtain energy from both the plant materials and animal’s meat so they can digest carbohydrates, proteins, fat, fiber, and metabolizes the nutrient and energy of the sources absorbed.
 Example – humans, dogs, cats, etc.

Hence, option C is the correct option for this question.

Note: All animals are composed of cells. Animals are the eukaryotic organisms which means their cells have well defined nucleus and membrane bound cell organelles. Their cells are surrounded by the extracellular matrix which is composed of collagen and elastic glycoproteins.
