A
Correct answer
Explanation
Fibrinogen is one of the important plasma proteins, which plays an important role in blood coagulation where it is converted by thrombin to fibrin. This is achieved through processes in the coagulation cascade that activates the zymogen prothrombin to the serine protease thrombin, which is responsible for converting fibrinogen into fibrin.
