To which chamber do the coronary veins drain deoxygenated blood?

Explanation:
Coronary veins return deoxygenated blood from the heart muscle to the right side of the heart. They mostly drain into the coronary sinus, which opens into the right atrium. The right atrium is the chamber that receives deoxygenated blood from systemic and coronary venous return, while the left atrium handles oxygenated blood from the lungs and the ventricles are the pumping chambers. So deoxygenated blood from the coronary veins enters the right atrium.
