Solution

option ,(b) pulmonary vein

Pulmonary veins are responsible for carrying oxygenated blood from the lungs back to the left atrium of the heart

The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium. The pulmonary artery channels oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium.
