Which of the following is an ARB?

Explanation:
Angiotensin II receptor blockers prevent angiotensin II from binding to AT1 receptors, which stops vasoconstriction and aldosterone-mediated sodium retention, leading to lower blood pressure. The medication that does this is losartan. Lisinopril is an ACE inhibitor, which lowers angiotensin II formation rather than blocking its receptor. Nifedipine is a calcium channel blocker, reducing calcium entry to relax vessels. Propranolol is a beta-adrenergic blocker, lowering heart rate and contractility through sympathetic pathways.
