  • Correct Answer

    Explanation

    The clotting of blood is a chain reaction initiated by the enzyme Thrombokinase produced by the platelets. This causes Prothrombin and calcium salts in plasma to join and produce thrombin. Thrombin combines with Fibrinogen to produce Fibrin threads which entangles the corpuscles  to create a clot.
