Which of the following is a common physical change observed in both girls and boys during puberty?

The correct option is B

Hair growth in various parts of the body

Puberty is the phase in life when a boy or girl becomes sexually mature. It is a process that usually happens between ages 10 and 14 for girls and ages 12 and 16 for boys. It causes physical changes and affects boys and girls differently. In girls, their hip bones widen and in boys, their shoulder bones broaden. In boys, hair grows in various parts of the body (pubic region, armpits, face, chest). In girls, hair growth is restricted to the armpits and pubic region.
