A) Beta-blocker
B) ACE inhibitor
C) Loop diuretic

B
Feedback:
The angiotensin-converting enzyme (ACE) inhibitor's primary action is to prevent the conversion of angiotensin I to angiotensin II, a potent vasoconstricting hormone in the blood. A beta-blocker blocks the beta-adrenergic receptors decreasing sympathetic nervous system stimulation. Loop diuretics excrete water from the loop of Henle, reducing circulating blood volume. Calcium channel blockers dilate coronary and peripheral arteries.
