B Correct answer
Explanation

Veins are the blood vessels that return blood to the heart from throughout the body. They carry deoxygenated blood (except pulmonary veins) back to the heart's right atrium. Arteries carry blood away from the heart, capillaries facilitate exchange, and lymph nodes are part of the immune system.
