Solution

The correct option is A to supply blood to heart muscles
Oxygenated blood is a requirement of all living tissues in the body for survival. The heart is the pumping organ of the body that is in a continuous state of activity and in need of an uninterrupted supply of oxygenated blood. The coronary arteries are the blood vessels which transport oxygenated blood to the heart muscles.
