The correct option is B deoxygenated blood, the lungs
Arteries carry blood away from the heart and veins carry blood towards the heart. All arteries carry oxygenated blood and all veins carry deoxygenated blood. Pulmonary artery and pulmonary vein are exceptions to these.
Pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. The pulmonary vein carry oxygenated blood from the lungs to the left atrium. The circulation which involves the movement of blood between the heart and the lungs is called pulmonary circulation.
