The correct answer is  The left umbilical vein becomes the round ligament of the liver after bih. The right umbilical vein did not leave a fibrous remnant because it was degenerated during the early embryonic period. The ductus venosus forms the ligamentum venosum; the ductus aeriosus forms the ligamentum aeriosum; Umbilical aery forms the medial umbilical ligament.
