A
lymphocytes
B
red blood cells
C
platelets
D
basophils
Explanation: 

Detailed explanation-1: -so that they stick to the injured area. The “glue” that holds platelets to the blood vessel wall is von Willebrand factor, a large protein produced by the cells of the vessel wall. The proteins collagen and thrombin act at the site of the injury to induce platelets to stick together.

Detailed explanation-2: -Platelets are tiny blood cells that help your body form clots to stop bleeding. If one of your blood vessels gets damaged, it sends out signals to the platelets. The platelets then rush to the site of damage and form a plug (clot) to fix the damage.

Detailed explanation-3: -Following vasoconstriction, exposed collagen from the damaged surface will encourage platelets to adhere, activate and aggregate to form a platelet plug, sealing off the injured area.

Detailed explanation-4: -Primary hemostasis (platelet clotting) Primary hemostasis is when your body forms a temporary plug to seal an injury. To accomplish that, platelets that circulate in your blood stick to the damaged tissue and activate.
