The best answer is A. As soon as the blood vessel wall is broken or damaged, a series of reactions activate platelets so that they stick to the site of injury. The platelets are able to hold to the blood vessel wall by means of a protein substance called von Willebrand's factor. Collagen and thrombin then act at the site of injury and induce platelets to clump or stick together, forming a mesh that plugs the broken part. Special clotting protein help sequester more platelets to the plug which finally becomes a blood clot.
