The correct option is C platelets
The blood has platelets which circulate around the body and plug the leaks by helping to clot the blood at these points of injury. When the cut occurs, signals are sent through the bloodstream, platelets in the blood release chemicals that notify other platelets nearby to become activated, or 'sticky.' Once activated, platelets change shape by growing small tentacles. This helps them to stick together. At the same time, other clotting factors get to work. A protein in the blood called fibrinogen becomes active as well. It is now called fibrin, and as its name suggests, it produces fibers. These strands cover the wound and create a web of sorts. The activated platelets continue to arrive on the scene through the bloodstream. They stick together and become caught in the web of fibrin. Red blood cells become trapped as well.
