Voice change during puberty occurs due to________.

Correct option is D

The correct answer is (D)   The development of larynx

1. Puberty is a stage of growth where the body experiences physical and sexual changes due to hormonal shifts.

2. During this phase, the larynx (voice box) becomes larger in both boys and girls, causing the vocal cords to grow longer and thicker. This leads to a deeper voice, especially noticeable in boys.

Puberty typically starts between ages 8 to 13 in girls and 9 to 14 in boys.

• Girls experience breast development and the start of menstruation.
• Boys develop larger testicles, a deeper voice, and a more muscular body.
