Carnivores:
Carnivores are animals that primarily feed on the flesh of other animals. They have specialized adaptations such as sharp teeth and claws to help them catch and kill their prey. Examples of carnivores include lions, tigers, and wolves.

Herbivores:
Herbivores are animals that eat only plants and plant-based materials. They have specialized digestive systems that allow them to break down and extract nutrients from plant matter. Examples of herbivores include cows, horses, and rabbits.

Omnivores:
Omnivores are animals that have the ability to eat both plants and the flesh of other animals. They have a more flexible diet and can adapt to a wider range of food sources. Omnivores have a combination of sharp and flat teeth to help them consume both plant and animal matter. Examples of omnivores include humans, bears, and pigs.

Explanation:
The correct answer to the question is option 'B' - Omnivore. Omnivores are the only category of animals that eat both plants and the flesh of other animals. They have a diverse diet that includes a combination of plant-based foods and animal protein. This allows them to obtain a wide range of nutrients from different sources.

Omnivores have adaptations that help them consume both plant and animal matter. For example, humans have both sharp incisor teeth for biting into fruits and vegetables, as well as flat molars for grinding and chewing plant matter. Bears have sharp teeth and claws for catching and killing prey, but they also consume a significant amount of plant material.

It is important to note that not all animals fit neatly into one category. Some animals may predominantly eat plants but also consume small amounts of animal flesh, while others may primarily consume meat but also eat some plant material. However, the term "omnivore" is used to describe animals that have a balanced diet and consume both plants and the flesh of other animals.
