Granulocytes are a type of white blood cell characterized by the presence of granules in their cytoplasm and play a significant role in the immune response. The three primary types of granulocytes are basophils, eosinophils, and neutrophils.

Basophils are involved in inflammatory responses and release histamine during allergic reactions. Eosinophils primarily target larger parasites and are also involved in allergic reactions and asthma. Neutrophils are the most abundant type of white blood cell and are critical for the body's defense against bacterial infections, quickly responding to sites of infection and inflammation.

In contrast, the other options presented consist of cell types that do not fit the classification of granulocytes. Macrophages, lymphocytes, and monocytes are part of the agranulocyte category; they are characterized by a lack of granules in their cytoplasm. Plasma cells and B cells are involved in the adaptive immune response as antibody-producing cells, while dendritic cells serve as antigen-presenting cells. Natural killer cells and T cells are also part of the agranulocyte population involved in the adaptive immune response. Thus, the classification of basophils, eosinophils, and neutrophils as granulocytes is accurate and
