    Platelets
  • D
    Macrophage
✓

Answer

Correct option: C.
Platelets

When an injury causes a blood vessel wall to rupture, platelets then rush to the site of damage and get activated.
They form a plug (clot) to fix the damage.
The process of spreading across the surface of a damaged blood vessel to stop bleeding is called adhesion.
This is because when platelets get to the site of the injury, they grow sticky tentacles that help them stick (adhere) to one another.
