Answer 1

Hint:
Complete answer:
Mammalian teeth are an important part of digestion. Teeth help in cutting, grinding and tearing of the food materials. Mammalia has four different types of teeth that are incisors, canine, molar and premolars. These teeth have different shapes and functions.
Incisors - They are sharp and blade-like structures. They help in cutting the food. For example, while biting an apple.
Canine- They are pointed and strong. They help with tearing the food. For example, while tearing the meat.
Molars- they are broad and flat on top. They were used for crushing and grinding food. Examples like grinding nutmeat.
Premolar – It has features of both canine and premolar. They can be used for tearing and grinding the food.
According to their feeding habits, animals are divided into herbivores, carnivores and omnivores.
Herbivores animals eat only plants and plant products such as fruits, seed, leaves etc. These animals usually have big front teeth called incisors. Incisors are used to grasp and cut food items (plant). Herbivores have a molar in the back, they help in grinding. Cow, deer, squirrels etc are examples of herbivores animals.
Carnivores are those animals which only eat animal meat. They need to cut and tear the animals’ meat therefore they have big canines and sharp molars. They have a small incisor in front. For example the lion, tiger, etc
Omnivore animals can eat both plants and animals. These animals eat different types of teeth therefore they have different types of teeth. They have incisors in front, for cutting plants and also canine for tearing meat. Bear is the best example of omnivores.

Hence the correct answer is option B.

Note: The size of the animals does not determine what they eat. Some biggest animals eat the only plant or smaller animals can be carnivores. Animal’s digestive tract will be designed according to the food they eat and also depending upon the type of food habits animal’s teeth are designed.
