Which class produces relaxation of blood vessels and lowers blood pressure?

Explanation:
Relaxation of vascular smooth muscle leads to vasodilation, which lowers systemic vascular resistance and thereby reduces blood pressure. The class that produces this exact effect is vasodilators; they widen arteries and ease blood flow, directly causing a drop in BP. Vasopressors do the opposite by constricting vessels and increasing BP, inotropes boost the heart’s pumping strength, and antihypertensive is a broad category of drugs that lower blood pressure by various mechanisms, not all via direct vessel relaxation.
