Which of the following are agranulocytes?
Basophils.
Monocytes.
Neutrophils.
Eosinophils.
The Correct Answer is B
Monocytes are a type of agranulocytes, which are white blood cells that lack visible granules in their cytoplasm.
Agranulocytes also include lymphocytes, which are involved in adaptive immunity.
Choice A is wrong because basophils are a type of granulocytes, which are white blood cells that have granules in their cytoplasm.
Granulocytes also include neutrophils and eosinophils, which are involved in innate immunity.
Choice C is wrong because neutrophils are also a type of granulocyte.
Neutrophils are the most abundant white blood cells and are responsible for phagocytizing bacteria and fungi.
Choice D is wrong because eosinophils are also a type of granulocytes. Eosinophils are involved in allergic reactions and parasitic infections.
Normal ranges for white blood cells vary depending on age, gender, and health status, but generally, they are between 4,000 and 11,000 cells per microliter of blood.

They also help to fight parasitic infections.
Choice B is wrong because allergens are not antibodies, but substances that cause an allergic reaction.
Choice C is wrong because the antibodies that belong to the immunoglobulin G group are not involved in allergic reactions, but in fighting bacterial and viral infections.
