Select the option that gives the number of various types of teeth in a complete set of permanent teeth in an adult human.

The dental formula of adult dentition in human is $\frac{2123}{2123}$. The dental formula summerises the number of each type of tooth (incisor, canine, premolar, molar) in each half of each jaw. This dental formula may also be represented as $\text{ i }\frac{2}{2}\text{, c }\frac{1}{1},\mathrm{pm}\frac{2}{2},\mathrm{m}\frac{3}{3}$. The number of incisors is (2+2)2 = 8; the number of canines is (1+1)2 = 4; the number of premolars is is (2+2)2 = 8; the number of molars is is (3+3)2 = 12.
