Final answer:
The fine hairs that cover much of the body surface are known as vellus hairs, distinguished from lanugo, which covers a fetus and is shed before birth.
Step-by-step explanation:
The fine "peach fuzz" hairs found all over much of the body surface are called C) Vellus hairs. Vellus hairs are different from lanugo, which is the fine, colorless hair that covers a fetus's face and body until it is shed close to the time of birth. Although vellus hair is also fine and colorless, it is not shed and continues to grow on parts of the body where it does not develop into thicker terminal hair, which is the coarser hair found on the scalp, eyebrows, and, during and after puberty, in areas such as the armpits and pubic region. Vellus hair plays a role in thermoregulation and sensation.
