Answer 1

The correct option is C Puberty

Human beings are complex animals and hence there is a distinct phase in their life cycle which marks the onset and attainment of sexual maturity. The period is called puberty. It usually starts at around 10-11 years of age in girls and at around 12-13 years of age in boys. It usually ends at around the 18th year of age in girls and the 19th year of age in boys.
Changes in boys: The boys suddenly grow in height dramatically. Voice becomes deep and the Adam’s apple becomes prominent. Shoulders become broad and the body becomes muscular. Facial hairs begin to grow. Hairs also grow under the armpit and in the pubic region.
Changes in girls: The voice becomes thin. Shoulders and hips become rounded. Breasts get enlarged. Hairs grow under the armpit and pubic region.
