✓ Correct answer: D. MetoprololAnswer: Metoprolol Metoprolol is a beta-blocker (class II) often used in the treatment of acute myocardial infarction (AMI) for reducing myocardial oxygen demand by decreasing heart rate and contractility. This helps in reducing the overall workload on the heart. Aspirin is an antiplatelet agent and is used to prevent further clot formation but is not a beta-blocker. Nitroglycerin is a nitrate used for vasodilation to relieve chest pain, not a beta-blocker. Atropine is an anticholinergic used to treat bradycardia, not a beta-blocker.
