Slowed heart rate and decreased contractility of the heart.

Answer and Explanation

The Correct Answer is D

A. Beta-adrenergic blockers primarily work by decreasing heart rate and contractility rather than directly affecting peripheral resistance.

B. Beta-adrenergic blockers decrease contractility and heart rate, rather than increasing them.
