(b) Thrombin
Explanation:
During blood clotting, lysis of fibrinogen to fibrin occurs by plasma thrombin. Later on fibrin entangles corpuscles to form a clot. Thrombin is not mormally found in circulating blood, but instead it is repressed by its inactive precursor prothrombin. The conversion of prothrombin to thrombin requires blood platelets, calcium ions and thromboplastin.
