The correct option is B Pulmonary arteries help the heart to transport blood to lungs for oxygenation.
An artery is a blood vessel that carries oxygenated blood away from the heart, and vein is a blood vessel that carries deoxygenated blood towards the heart. But pulmonary artery is the only artery that carries deoxygenated blood from the heart to the lungs for oxygenation. The pulmonary veins transfer oxygenated blood from the lungs to the heart.
