Solution

The correct option is D Coronary arteries
  • The heart is a muscular pump, that needs a continuous supply of oxygen.
  • It gets oxygen from the blood, which flows to the heart muscle through arteries on its surface. These arteries are called coronary arteries.
  • A heart attack happens, when there is a sudden complete blockage of an artery that supplies blood to an area of the heart.
  • As a result, some of the heart muscle begins to die.
