Solution

The correct option is C Ca $^{+ +}$ and vitamin K
Calcium ion and vitamin K are needed for blood clotting. Coagulation (thrombogenesis) is the process by which blood forms clots.
Vitamin K adds a carboxyl group to multiple factors of the coagulation cascade. In adding the gamma-carboxyl group to glutamate residues on the immature clotting factors, Vitamin K is itself oxidized.
Calcium mediates the binding of the complexes to the phospholipid surfaces expressed by platelets.
Hence, correct answer is option B.
