Solution

The correct option is B Pre­molars
The teeth in children are not permanent and they are deciduous in nature. Thus the set of teeth which is deciduous is called milk teeth. Whereas the teeth that grow after the shedding of the milk teeth are called the permanent teeth. The human adult has a set of permanent teeth. There are four kinds of teeth - incisors, canines, premolars and molars. Incisors are usually specialised for cutting. Canines lie immediately behind the incisors and are used for tearing and ripping the food. Premolars and molars are called cheek teeth which are broad and strong. Milk teeth of humans include 8 incisors, 4 canines, 0 premolars and 8 molars. The permanent teeth have 8 incisors, 4 canines, 8 premolars and 12 molars. Thus premolars would most likely be absent in the two year old kid as he is still having the milk teeth.
