Answer: (A), (B), (D)

The growth of hair on chest and face

Secondary sexual characteristics are any physical characteristics developing at puberty which distinguish between the sexes but is not directly involved in reproduction.

Changes in boys include:
$\bullet$ Development of heavier muscular body, wide shoulders, and narrow hips.
$\bullet$ Enlargement of voice box leading to much deeper voice.
$\bullet$ Maturation of testis.
$\bullet$ The growth of hair on chest.
$\bullet$ Enlargement of Adam’s apple.

Hip becomes wider in girls during puberty, not in boys.
