Which fetal vessel gives rise to the round ligament of the liver?

Explanation:
The round ligament of the liver is the fibrous remnant of the umbilical vein. In fetal life the umbilical vein carries oxygenated blood from the placenta to the fetus, and after birth this vessel closes and becomes a fibrous cord within the falciform ligament, known as the round ligament (ligamentum teres hepatis). The other vessels have different postnatal remnants: the ductus venosus becomes the ligamentum venosum, the umbilical arteries become the medial umbilical ligaments, and the portal vein is a main hepatic vessel formed from embryonic vitelline vessels, not the source of the round ligament.
