B. Canines and premolars
C. Premolars and molar
D. Canines and molars

Answer 1

Teeth are the hardest substances that are found in humans and animals. The teeth are present in the mouth and play an important role in the digestion of food as it chews the food for proper digestion. The teeth are made up of calcium phosphate.

Complete answer:
A tooth is embedded into the gum socket which is present in the maxilla or the upper jaws and the mandible or the lower jaw. The part of the tooth that is present above the gum is known as enamel and it is the hardest part of the teeth. Other parts of the teeth are dentin, cementum and the pulp.
In humans, there are four types of teeth on the basis of their shape and position. The different types of teeth found in humans are incisors, canines, premolars and molars. The premolars and the molars form the cheek teeth in mammals. Cheek teeth are multi cuspidate or possess many fold or tubercles. The premolars are situated after the canines towards the interior and next lies the molars.
Premolars are the bicuspids and are located between the canine and the molar teeth. There are a total of eight premolar humans which are situated in both the jaws and contain two cusps. The premolars are considered to be the transitional teeth and possess properties of both molars and canines.
Molars are the grinding teeth and are large, flat teeth found at the back of the mouth. The molars are very much developed in mammals and are used for grinding of food during chewing. Molars contain about four to five cusps.
Incisors are the frontal teeth and are eight in number in humans. They serve to cut off pieces of food as well as help in the gripping of the food items.
Canines are the teeth that are present two in the upper and two in the lower jaws. They are pointed and are found lateral to the incisors and function in tearing of flesh.

Hence, the correct answer is option (C).

Note: Teeth are present in the mouth and function to mechanically break down the food items by grinding, crushing and cutting them into smaller parts that are useful in digestion and swallowing. The premolars and the molars are known as the cheek teeth. The cheek teeth are also known as the post canines.
