None of the above
Explanation: 

Detailed explanation-1: -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. The process of spreading across the surface of a damaged blood vessel to stop bleeding is called adhesion.

Detailed explanation-2: -If your platelet level becomes too low, your doctor can replace lost blood with transfusions of packed red blood cells or platelets. Medications. If your condition is related to an immune system problem, your doctor might prescribe drugs to boost your platelet count. The first-choice drug might be a corticosteroid.

Detailed explanation-3: -Platelets help prevent blood loss at sites of vascular injury. To do this, they adhere, aggregate and form a procoagulant surface favoring thrombin generation and fibrin formation.

Detailed explanation-4: -Platelets are found in your blood and play an important role in healing injuries. Growth factors and proteins found in the platelets speed up the body’s tissue repair process, especially in degenerative tissues (muscles, tendons and ligaments) that have not healed correctly initially after an injury or from overuse.
