Answer
B. Pulmonary veins.
Explanation
Veins are blood vessels that carry blood towards the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart. In this case, the question is asking for the veins that carry oxygenated blood. Subclavian veins are two large veins, one on either side of the body, that return blood from the arms to the heart. They carry deoxygenated blood.Coronary veins are veins that drain deoxygenated blood from the heart muscle (myocardium) and carry it back to the heart.The vena cavas are two large veins (the superior vena cava and the inferior vena cava) that return deoxygenated blood from the body back to the heart.Pulmonary veins are the veins that transfer oxygenated blood from the lungs to the heart. They are the only veins in the body that carry oxygenated blood.
