Which of the following is the correct sequence of steps in hemostasis?

Rationale: A. Vascular spasm occurs first. B. Coagulation is the final step, not the first. C. Matches the physiological sequence of hemostasis. Hemostasis is the process that stops bleeding following vascular injury, and it occurs in a specific sequence of steps: Vascular spasm – The immediate constriction of the blood vessel to reduce blood flow and limit blood loss. This is the first response to injury. Platelet plug formation – Platelets adhere to the exposed collagen of the damaged vessel, aggregate, and form a temporary plug. Coagulation (blood clotting) – The coagulation cascade is activated, leading to fibrin formation, which stabilizes the platelet plug and forms a durable blood clot. D. Platelet plug formation occurs after vascular spasm, not before.
