Question

During adolescence, several changes occur in the human body. Find out the change which is associated with sexual maturation in boys.

• A. Loss of milk teeth
• B. Increase in height
• C. Cracking of voice
• D. Weight gain

Answer 1

Answer: (C)

Cracking of voice

At puberty, the voice box or the larynx begins to grow. Boys develop larger voice boxes. The growing voice box in boys can be seen as a protruding part of the throat called Adam's apple.

Other changes are not associated specifically with puberty, e.g. an increase in height and weight can occur before puberty also and similarly loss of milk teeth is also not associated with puberty.

Therefore, the correct answer is option C.
