Step 1: Understanding blood clotting.
Blood clotting is facilitated by platelets (thrombocytes) that aggregate at the site of injury and release clotting factors.
Step 2: Explanation of incorrect options.
- WBC (White Blood Cells) are involved in immunity, not clotting.
- RBC (Red Blood Cells) transport oxygen but do not play a role in clotting.
- None of these is incorrect because platelets are responsible for clotting.
