The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Heparin is also known as blood thinner and is responsible for preventing coagulation of blood. Prothrombinase is the coagulation factor that is converted to an enzyme that converts prothrombin to thrombin in a reaction that depends on calcium ions and other coagulation factors thereby helping in coagulation of blood.
