Verified step by step guidance

Step 1: Understand the term 'granulocyte.' Granulocytes are a type of white blood cell characterized by the presence of granules in their cytoplasm. They play a role in the immune response.

Step 2: Review the structural features of neutrophils. Neutrophils are granulocytes with a multi-lobed nucleus (typically 3-5 lobes) and pale-staining cytoplasmic granules. They are the most abundant type of granulocyte and are involved in phagocytosis and the destruction of pathogens.

Step 3: Compare neutrophils to other granulocytes. Eosinophils have bilobed nuclei and granules that stain red or orange with eosin dye, while basophils have large, dark-staining granules that obscure the nucleus. Monocytes, on the other hand, are agranulocytes and lack cytoplasmic granules.

Step 4: Eliminate incorrect options based on the description. Monocytes are not granulocytes, and eosinophils and basophils do not have pale cytoplasmic granules or multi-lobed nuclei. This leaves neutrophils as the correct answer.

Step 5: Confirm the answer by matching the characteristics provided in the question (multi-lobed nucleus and pale cytoplasmic granules) to the features of neutrophils.
