Correct Option (c) Premolars


In human beings, after birth the first set of teeth that develops are deciduous teeth or temporary teeth. These are 20 in number. The dental formula of child is 2102/2102.

Thus, they have 2 incisors, 1 canine, 0 premolars and 2 molars. Therefore, the baby boy would not  have premolars.
