Solution

The correct option is A

Pulmonary vein


The pulmonary vein carries oxygenated blood from the lungs to the left atrium of the heart. Oxygenated blood from the left atrium goes to the left ventricle and then is pumped to all body organs. Pulmonary vein is the only vein that carries oxygenated blood. Remaining all other veins carry deoxygenated blood.
