Which is a characteristic of the fetus at 20 weeks' gestation?

b. Vernix caseosa covers the entire body of the fetus.
c. Brain development of the fetus is complete.

B
At 20 weeks, vernix caseosa covers the entire body of the fetus. At 24 weeks, alveoli are present in the lungs and surfactant is just beginning to be produced. Rapid brain growth occurs between 17 and 19 weeks, but the brain continues to grow after that. Sounds outside the mother's body are still quite muffled at this point.
