Step-by-step explanation:
The peak rate of pubertal change occurs at 13 years for girls and 14½ years for boys. This represents the age at which the physical and hormonal changes associated with puberty are at their maximum intensity.
During puberty, girls typically experience the onset of menstruation and other physical changes around the age of 13, while boys undergo significant growth spurts and the development of secondary sexual characteristics, such as facial hair, around the age of 14½. It's important to note that individual variations exist, and the stated ages are averages based on biological norms.
Option A is correct.
