Which of the following veins transports oxygen-rich blood rather than blood low in oxygen?

Explanation

The pulmonary vein is unique among veins because it carries oxygenated blood from the lungs to the left atrium of the heart. In contrast, the superior vena cava and inferior vena cava return deoxygenated blood from the upper and lower parts of the body, respectively. Similarly, the hepatic vein carries deoxygenated blood from the liver back to the heart. Therefore, all listed veins carry deoxygenated blood except the pulmonary vein.
