Puberty starts in boys

The correct option is B Later than girls
Puberty is the process where the child undergoes several physical changes due to fully developed sexual organs. Two of the most significant differences between puberty in girls and puberty in boys are the age at which it begins, and the major sex hormones involved, the testosterone and the estrogens.
Girls typically begin the process of puberty at age 10 or 11 and boys at ages 11 or 12.
So, the correct answer is option A.
