Solution

The correct option is A A and C
During the clotting process, injured cell and blood platelets secrete thromboplastin which convert plasma protein prothrombin into thrombin. Thrombin then converts plasma protein fibrinogen into fibrin which being insoluble forms mesh work enclosing RBCs to form a clot.
Thus, the correct answer is option A.
