The correct answer is B. clotting of blood

Prothrombin is transformed into thrombin by a clotting factor known as factor X or prothrombinase.

Thrombin then acts to transform fibrinogen, also present in plasma, into fibrin, which, in combination with platelets from the blood, forms a clot (a process called coagulation).
