Solution
The correct option is D Platelets
There are various theories which are proposed by different scientists on the phenomenon of blood clotting. The theories explain the components involved and the mechanisms involved in blood clotting. According to Best and Taylor's Theory, four components are involved in blood clotting. These are prothrombin, thromboplastin, calcium ions, and fibrinogen. Thromboplastin released from damaged tissues active the prothrombin to thrombin in the presence of calcium ions. The thrombin activates fibrinogen to fibrin which forms the clot. So, there is no involvement of the platelets in clotting according to Best and Taylor's theory. Thus, the correct answer is option C.
