Final Answer :
B
Explanation :
Microglia are the primary immune defense cells in the central nervous system (CNS), including the brain. They become activated in response to infection, injury, or disease, proliferating and mobilizing to the site of damage to engulf and destroy pathogens, such as microbes, through phagocytosis.
