Solution

The correct option is B Prothrombin
During the process of blood clotting, platelets release thromboplastin which converts prothrombin into thrombin. This thrombin in presence of calcium ions is responsible for converting fibrinogen into insoluble fibrin, thus forming a clot.
So, the correct answer is 'Prothrombin'.
