Answer 1

Answer: (A)

Puberty is the process that involves physical changes through which a child's body, matures into an adult body. The changes involved in boys include broader shoulders and chest. By the end of puberty, men have heavier bones and nearly twice as much skeletal muscle. The skin starts responding to the male hormones and develops facial hairs and also pubic hairs. These hormones also increase the secretion of oil or sebum from the skin resulting in acne. Broadening of the hip region and development of the mammary gland exclusively occur in females, during puberty.

Therefore, the correct answer is option A.
