Answer 1

Hint: Teeth form an integral part of our body, they play a very important role in eating food. There are different kinds of teeth made for different purposes. The vegetarian and non-vegetarian have a slight difference in their teeth shape. Enamel forms the hardest part of the body.

Complete answer:
There is a set of 32 teeth in an adult human being’s jaw. They are composed of molars, premolars, canines and incisors. Some teeth are modified to perform some other particular function.
One of these modified teeth is carnassial teeth. They have the function to tear the body of the prey. They are certainly the modifications in the carnivorous animals. They are the paired molars or premolars. They have self-sharpening edges.
Canines are four in number in the whole teeth set. They are long and pointed behind incisors. They are used for tearing the prey.
Carnassial teeth are the last premolar of the upper jaw and the first molar of the lower jaw, which makes the option C correct. They form a pair of the upper and lower molar and premolars.

So the answer is option C: Last premolar of the upper jaw and first molar of the lower jaw.

Note:
Premolar teeth are the bicuspids between the canine and molars. There are 2 premolars per quadrant of normal human beings. The molars are the last teeth of the jaw. They are broader and flatter with 4-5 cusps. They both are used in grinding and chewing of the food. It is very important to take care of our teeth to pursue a healthy life.
