The correct answer is D. This downy, unpigmented hair is the first type of hair that grows from hair follicles. It can be found everywhere on a baby’s body, except on the palms, lips, and soles of the feet. It starts to develop around the fifth month in pregnancy but disappears at birth. Terminal hair, lanugo, and vellus hair do not appear on a fetus.
