The umbilical vein carries highly oxygenated blood from the placenta to the fetus, making it the correct answer.

The pulmonary arteries carry deoxygenated blood from the heart to the lungs, and the pulmonary vein carries oxygenated blood from the lungs to the heart, but neither of these vessels are involved in fetal circulation.
