Solution

The correct option is D Pulmonary vein
The pulmonary vein connects the lungs and the heart and carries the oxygenated blood from the lungs to the left atrium of the heart from where it moves to the right atrium and is distributed to the rest of the body through the aorta. The pulmonary vein is the only vein that carries oxygenated blood while all other veins carry deoxygenated blood.
So, the correct answer is option D.
