Blood coagulation is initiated by either the intrinsic or extrinsic pathway. the final step inboth pathways would be:

a)activation of factor xii

b)deactivation of fibrinogen, preventing the conversion to fibrin

c)activation of factor x, leading to conversion of prothrombin ii to thrombin iia

d)activation of factors vii, x, v, and ii

The final step in both pathways would be the activation of factor X, leading to conversion of prothrombin II to thrombin IIa. Option C.

Explanation: blood coagulation is the processes that leads to blood clot formation. The blood clot formed is made up of fibrin and platelets, which forms hemostatic plug over a wound site. The blood coagulation is made up of two partways that led to the formation of clot. The intrinsic pathway also called contact activation pathway and the extrinsic pathway which is also known as the tissue factor pathway. The both pathways are connected by a common pathway whereby factor X is activated leading to leading to conversion of prothrombin II to thrombin IIa. Thrombin then converts fibrinogen to fibrin( blood clot). I hope this helps. Thanks.
