A. Canine
B. Incisor
C.Molar
D.Premolar

Answer 1

Hint: The adult human has a heterodont dentition where there are thirty-two teeth with four types which are the incisors (sharp), canines (pointed), premolars, and molars.

Complete answer: Humans have thirty-two permanent teeth. They are of four types incisors, canines, molar, and premolar. The incisors are the teeth which are located at the upper and the lower jaws, their main function is biting and cutting of food. The central incisors are on the midline of either side, and the lateral incisors are the two which are adjacent to the central incisors, they have a sharp edge that helps in biting off the food. The canines are the four in the oral cavity where the two are present in the maxillary arch the other two are present in the mandibular, the canines are behind and are adjacent to the lateral incisors, these help in the tearing of the food as they have a single pointed root which is the longest in the oral cavity, and also are the corners of the mouth. The molars are the posterior teeth that have a broad and flat surface and also have four to five cusps present; their main function is the grinding of food. In permanent dentition, there are twelve molars wherein each of the quadrants there are three. The molars are named as first molars, second molars, and the third molar these names are named with the closest midline. The premolars are located behind the canines and adjacent to them. They are designed to crush the food, there are eight premolars in the oral cavity.
Hence, the correct option is ‘B’.

Note: Humans have a heterodont dentition, where the incisors have the sharp edges which are used for biting or cutting off food, the canines are designed for tearing the food, the premolars crush the food and the molars grind the food in the oral cavity.
