Which sequence is correct for the following events fibrinogen fibrin clot retraction formation of thromboplastin and prothrombin- thrombin?

The correct sequence of events is: formation of thromboplastin, conversion of prothrombin to thrombin, conversion of fibrinogen to fibrin, and finally, clot retraction. Thromboplastin initiates the coagulation cascade, leading to thrombin production, which then converts fibrinogen into fibrin, forming the clot that subsequently retracts.
