The correct option is: A) the coronary arteries

Explanation:

Coronary circulation is a part of the systemic circulatory system that is responsible for supplying oxygenated blood and draining the deoxygenated blood from the heart muscles.

In this circulatory system, the blood vessels responsible for supplying blood to the heart muscle, myocardium, are called coronary arteries. Whereas, the cardiac veins are responsible for draining away the deoxygenated blood from the heart muscles.
