Coagulation (also known as clotting) is the process by which blood changes from a liquid to a gel, forming a  clot. The  activation  of some of the enzymes in the coagulation cascade is dependent on vitamin K. In the presence of other plasma proteins (clotting factors) and calcium ions, this leads to the activation of a protein called as factor X. 
Fibrinogen or factor I is a blood plasma protein that is made in the liver. It is one of 13 coagulation factors responsible for normal blood clotting. 
Vitamin D is required for the formation of strong bones and does not play any role in blood clotting. 
Hence, the correct answer is option 'B'.
