The correct answer is three arteries.
Arteries are the blood vessels that carry blood away from the heart. More specifically, the aorta is the main artery that carries oxygenated blood from the heart to the rest of the body. Veins carry blood back to the heart, and capillaries are the small blood vessels where the exchange of oxygen and carbon dioxide occurs. The term "elastic" refers to a type of artery (elastic arteries) that can stretch to accommodate the pulse of blood pumped from the heart.
