Final Answer : D, Explanation :  At the fifteenth week of gestation, the fetus is covered with a fine, downy hair called lanugo. This hair is usually shed before birth, but may be present in premature babies or those with certain genetic conditions. Vernix is a white, waxy substance that covers the skin of the fetus and helps protect it from amniotic fluid. Vellus hair is the fine, soft hair that covers most of the body in adults, while fontanelle refers to the soft spots on the skull of an infant.
