Solution

The correct option is D Number and type of teeth in one half of both jaws
Humans have two types of dentition - deciduous and permanent dentition. Deciduous dentition is found in children and permanent dentition is found in adults. Dental formula gives a complete idea about the total number and types of teeth in one half of both the jaws.
Deciduous dentition formula = I (2/2) C (1/1) PM (0/0) M(2/2)
Permanent dentition formula = I (2/2) C (1/1) PM(2/2) M(3/3)
Here, I = Incisors, C = Canine, PM = Pre-Molars, and M = Molars.
So, the correct answer is option D.
