In fetal life, there is a direct shunt from the umbilical vein to the inferior vena cava called the ductus venosus, which bypasses most of the liver to deliver well-oxygenated blood to the heart and brain. The ligamentum venosum is the fibrous remnant left after birth of that ductus venosus, so the question asks you to recall that the ligamentum venosum corresponds to the ductus venosus during fetal life. The other vessels have different roles: the umbilical vein carries oxygenated blood from the placenta to the fetus (and becomes part of the round ligament after birth), the ductus arteriosus shunts blood from the pulmonary artery to the aorta (and becomes the ligamentum arteriosum), and the portal vein brings blood from the GI tract to the liver (not a fetal shunt remnant).
