Which blood particles help in clotting of blood?
Answer and explanation
Correct answer: Platelets
The governing concept is blood clotting, or coagulation, which prevents excessive blood loss after an injury. When a blood vessel is damaged, platelets gather at the site and help form a temporary plug. They also release substances that support the clotting reaction and formation of fibrin threads. Therefore, option A is correct. Red blood cells carry oxygen, white blood cells defend against pathogens, and plasma is the liquid part of blood; these are not the main clot-forming particles.
