✓

Answer

  1. Fibrin

Explanation:

When blood vessels are cut or damaged, the loss of blood from the system must be stopped before shock and possible death occur. This is accomplished by solidification of the blood, a process called coagulation or clotting. A blood clot consists of a plug of platelets and network of insoluble fibrin molecules. It does not contains thrombin, fibrinogen and prothrombin.
