Solution

The correct option is C Clotting of blood
Platelets are tiny blood cells that help stop bleeding by forming clots. At the time of injury, when any blood vessels get damaged, it sends out signals. These signals are received by platelets and they, along with fibrinogen, a protein present in plasma form a clot and heal the wound.
