Correct Answer: Option A

Explanation

The coronary artery is specifically responsible for supplying oxygenated blood to the tissues and muscles of the heart itself. 

The coronary arteries are the first branches to exit the aorta immediately after it leaves the left ventricle. Because the heart is a highly active muscle, it cannot receive enough oxygen simply from the blood passing through its chambers; instead, it relies on this dedicated network of coronary vessels to deliver blood directly to the myocardium (heart muscle). 

B.The pulmonary artery carries deoxygenated blood away from the heart (right ventricle) to the lungs.

C.The renal artery carries blood away from the heart (via the aorta) to the kidneys.

D.The aorta is the main and largest artery that carries oxygenated blood away from the heart to be distributed to the rest of the body.
