Explanation

Option B is correct.Thrombin is used locally to stop bleeding. It is a protein that is produced by the liver and is involved in the clotting of blood. Thrombin is used in surgery to stop bleeding from small cuts or incisions. It is also used to treat bleeding disorders, such as hemophilia. Thrombin works by converting fibrinogen, a soluble protein in the blood, into fibrin, an insoluble protein. Fibrin forms a mesh that traps red blood cells and platelets, creating a clot that stops the bleeding.
