The correct answer is B) Calcium
Blood clotting is a process that helps to stop bleeding when a blood vessel is injured. It is a complex process that involves several factors and enzymes.
Calcium plays an important role in blood clotting, it is an essential component of the clotting cascade, that is a series of chemical reactions that lead to the formation of a blood clot.
Calcium ions are necessary for the activation of clotting factors such as Factor V, Factor VIII, and Factor IX.
Calcium ions are also necessary for the formation of prothrombin activator, which converts prothrombin to thrombin, an enzyme that converts fibrinogen to fibrin, which forms the basis of the blood clot.
