The correct answer is D. Neutrophils.
Neutrophils are the most abundant type of white blood cell (WBC) in the blood, making up about 50-70% of all WBCs. They are phagocytes, which means they can engulf and destroy bacteria and other foreign particles. Neutrophils are also the first type of WBC to arrive at the site of an infection, where they play a key role in the body’s immune response.
Eosinophils make up about 2-4% of all WBCs. They are involved in allergic reactions and parasitic infections.
Basophils make up about 0.5-1% of all WBCs. They release histamine and other chemicals that are involved in allergic reactions.
Lymphocytes make up about 20-30% of all WBCs. They are involved in the body’s immune response to infection and disease.
