Solution
The correct option is DCa++ Blood clotting (coagulation) is the process by which blood vessels repair ruptures after injury. Calcium works together with vitamin K and a protein, called as fibrinogen in the clotting cascade, which forms fibrin. The fibrin hardens very quickly to form a scab over the wound.
