Which of the following plasma protein is responsible for blood coagulation?

A blood clot, also known as a thrombus, is a solid mass of coagulated blood that forms in the circulatory system to stop bleeding from a damaged blood vessel. The formation of a blood clot involves a complex process known as coagulation, which involves the activation and interaction of various plasma proteins and blood cells called platelets. 

Fibrinogen is a plasma protein that acts as a precursor for the formation of a blood clot. In response to injury, fibrinogen is converted to fibrin by the action of clotting factors, which leads to the formation of a stable clot that helps stop bleeding. Fibrin fibers interlock to form a mesh-like structure that traps red blood cells and platelets, creating a temporary barrier that seals the damaged blood vessel.
