- DHigh pitched voice
Correct answer
D. High pitched voice
Step-by-step solution
Secondary sexual characteristics are features that appear during puberty and distinguish the two sexes of a species, but are not directly part of the reproductive system.
During puberty in boys, secretion of testosterone leads to various changes:
The skin becomes oily due to increased activity of sweat and sebaceous glands.
Hair develops in the underarms, pubic region, face, and chest.
The larynx (voice box) grows larger, causing the voice to deepen and become low-pitched.
A high-pitched voice is a secondary sexual characteristic observed in girls, not boys.
Therefore, a high-pitched voice is not a secondary sexual character in boys.
