• D. It is a coronary vein blocked by a parasite (blood fluke) that is being removed.

Answer 1

The correct option is B It is a coronary artery which is blocked by a plaque and the same is being cracked.

It is a coronary artery having arteriosclerosis. It is the hardening of arteries and arterioles due to the thickening of the fibrous tissue, and the consequent loss of elasticity. In this disease, calcium salts precipitate with the cholesterol of the formed or forming plaque. This calcification ultimately makes the wall of arteries stiff and rigid. The blood from such ruptured vessels may clot or block the blood flow. Such a clot in the coronary artery may lead to a heart attack or even death.

So, the correct answer is 'It is a coronary artery which is blocked by a plaque and the same is being cracked'.
