• B. (I) Aorta, (II) Hepatic portal vein, (III) Inferior vena cava
• C. (I) Hepatic portal vein, (II) Inferior vena cava, (III) Aorta
• D. (I) Hepatic portal vein, (II) Aorta, (III) Inferior vena cava

Answer 1

The correct option is D

(I) Hepatic portal vein, (II) Aorta, (III) Inferior vena cava

As depicted in the image the aorta carries oxygenated blood away from the heart. Aorta branches to form various arteries. The artery which carries oxygenated blood to the liver is called the hepatic artery. The portal vein carrying blood from the digestive tract to the liver is called the hepatic portal vein. Blood from the liver through hepatic veins flow into the inferior vena cava, which carries blood to the right atrium.
