a. 26
b. 30
c. 32
d. 28

Answer 1

A human's second set of teeth, known as the permanent teeth, consists of 32 teeth, which replace the first set of 20 deciduous teeth during middle childhood.

Step-by-step explanation:

Humans have two sets of teeth over their lifetime. The first set is known as deciduous teeth, sometimes called milk teeth or baby teeth, and consists of 20 teeth that emerge in infancy and early childhood. These teeth are eventually lost and replaced by the second set, the permanent teeth. The complete set of permanent teeth includes 32 teeth. These are composed of 8 incisors, 4 canines, 8 premolars, and 12 molars, which include the 4 wisdom teeth that typically emerge in late adolescence or early adulthood.

Referring to the choices provided in the question, the correct answer is that the final set consists of 32 permanent teeth (option c).
