Solution

The correct option is A 2 I, 1 C, 2 P, 3 M
The permanent or adult dental formula of humans is $I \frac{2}{2}, C \frac{1}{1}, P \frac{2}{2}, M \frac{3}{3}$ = $\frac{8}{8} (\frac{8}{8} \times 2$ = $\frac{16}{16}$ = 32).
This is the notation format for dental formulas in mammalogy. It shows the number of incisor 2, canine 1, premolar 2 molar 3 in each half upper and half lower jaw with 32 teeth in a buccal cavity.

Thus, the correct answer is option B.
