The correct option is C Pulmonary artery
The superior vena cava brings oxygen deficient blood from the body into the right atrium. The pulmonary artery carries this oxygen deficient blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium. The aorta is the main artery that carries oxygenated blood away from the left ventricle to the rest of the body.
