When the Palmer Notation System (PNS) is used:

The correct answer is option b. In the Palmer Notation System, the first digit indicates the quadrant, and the second digit indicates the tooth within the quadrant, with numbering from the midline to the posterior. For example, a tooth numbered 13 would indicate the upper right first molar.

Dental formula: In each quadrant of the mouth, there are eight teeth: two incisors, one canine, two premolars, and three molars. The dental formula 2:1:2:3 represents this distribution of teeth.
