Question

Final Answer : A,B,C , Explanation :  Cardiac efficiency gradually declines as the heart muscle loses contractile strength and heart valves become thicker and more rigid.The peripheral vessels become less elastic,which creates more resistance to ejection of blood from the heart.As a result of these changes,the heart becomes less able to respond to increased oxygen demands,and it needs longer recovery times after responding.
