Which pairing is correct for electrolytes involved in blood coagulation?

Explanation:
Coagulation relies on divalent cations to drive the cascade. Calcium ions are essential cofactors in many steps, enabling coagulation factors to bind to phospholipid surfaces and participate in activation events like prothrombin to thrombin and ultimately fibrin formation. Magnesium also serves as a cofactor for several coagulation enzymes and supports proper enzyme activity and platelet function, making it the second electrolyte commonly involved in coagulation. Potassium and chloride do not serve as primary cofactors in the coagulation cascade. Therefore, calcium and magnesium best fit the electrolytes involved in blood coagulation.
