Best answer
Correct choice is (c) Valves

Explanation: The valves of the heart regulate the incoming and outgoing of the blood which can cause mechanical stress to them and lead to stenosis. Due to this stenosis, the valves do not close properly and so regurgitation of blood or dripping of blood may happen which can cause cardiac problems. Once these valves are replaced, the normal functions of the heart can be recovered.
