    • A.

      Coagulation

    • B.

      Fibrinolysis

    • C.

      Hemostasis

    Correct Answer
    C. Hemostasis
    Explanation
    Hemostasis is the correct answer because it refers to the process of stopping bleeding and repairing blood vessels after an injury. This process involves vasoconstriction to reduce blood flow, formation of a platelet plug to seal the damaged blood vessel, and blood clotting to reinforce the plug. Coagulation refers specifically to the blood clotting process, while fibrinolysis is the breakdown of blood clots. Hemostasis encompasses both of these processes and is essential for maintaining the integrity of the circulatory system.
