The Correct Option is C
Solution and Explanation
Cardiotonic agents are drugs that increase the efficiency and improve the contraction of the heart muscle, typically used in heart failure. Beta-adrenergic antagonists (beta blockers) actually reduce heart rate and contractility, which is contrary to the action of cardiotonic agents.
