D Correct answer
Explanation

Platelets (thrombocytes) are the blood components responsible for clotting - they gather at wound sites, release clotting factors, and form platelet plugs. RBCs carry oxygen, lymphocytes are white blood cells for immunity, and monocytes are also white blood cells that fight infection but don't directly clot blood.
