Explanation:
- Inferior vena cava (A): Carries deoxygenated blood from the lower part of the body to the right atrium of the heart.
- Pulmonary vein (B): Carries oxygenated blood from the lungs back to the left atrium of the heart.
- Pulmonary artery (C): Carries deoxygenated blood from the right ventricle to the lungs for oxygenation.
- Superior vena cava (D): Carries deoxygenated blood from the upper part of the body to the right atrium of the heart.
Thus, the pulmonary vein is the vessel that carries oxygenated blood.
