Solution

The correct option is B

B & C


Heart muscles are continuosly supplied with blood by the coronary arteries. Cardiac veins collect blood from heart walls and empty it into the right auricle. Any block in the coronary artery decreases the blood supply to the heart muscles. Reduced blood supply reduces the amount of oxygen available to the muscles for respiration. This results in pain in the chest which is medically termed 'Angina pectoris'
