Answer: C) Blockade of beta-adrenergic receptors in the heart
g g g g g g g g




Rationale:
g



Beta-blockers work by blocking beta-adrenergic receptors in the heart. This
g g g g g g g g g



reduces heart rate, myocardial contractility, and decreases cardiac output, which
g g g g g g g g g g



helps to lower blood pressure and manage conditions like hypertension, angina,
