Which blood component is NOT correctly matched with its function?
A) Erythrocytes - transport oxygen
B) Leukocytes - protect against disease
C) Platelets - phagocytize bacteria
D) Plasma proteins - maintain blood osmotic pressure; involved in clotting
E) Monocytes - become macrophages
Platelets
Small blood cells essential for blood clotting, helping to stop bleeding by clumping together and forming plugs in blood vessel injuries.
Phagocytize
The process by which cells, especially immune system cells like macrophages, ingest or engulf other cells, bacteria, or particles.
Monocytes
A type of white blood cell that plays a significant role in immunity, inflammation, and tissue repair by differentiating into macrophages and dendritic cells.

Final Answer :
C
Explanation :
Platelets are primarily involved in blood clotting (hemostasis) by clumping and forming plugs in blood vessel holes. They do not phagocytize bacteria; that function is performed by certain types of white blood cells (leukocytes), such as neutrophils and macrophages.
