Which blood component mainly helps in blood clotting?
Answer and explanation
Correct answer: Platelets
When a blood vessel is damaged, platelets gather at the injured site and become involved in a chain of reactions that forms a fibrin mesh. This mesh traps blood cells and produces a clot, helping seal the wound and limit blood loss. Therefore, option A is correct. Red blood cells mainly transport respiratory gases, white blood cells defend against pathogens, and water in plasma is a transport medium rather than the main clotting component.
