Answer:
The correct answer is - macrophage.
Step-by-step explanation:
Macrophages are the white blood cells that are phagocytic in nature and involve in the detection and destruction of the microbes such as bacteria. The macrophage is a Greek word that means large eater or big eater that explains its cell eating property.
