Lymphocytes and Monocytes belong to which class of white blood cells?

Explanation:
White blood cells are grouped by whether their cytoplasm shows visible granules under standard staining. Granulocytes—neutrophils, eosinophils, and basophils—have noticeable cytoplasmic granules. Lymphocytes and monocytes lack these visible granules, so they are classified as agranulocytes. Erythrocytes are red blood cells, and platelets are cell fragments involved in clotting, not white blood cells. Hence, lymphocytes and monocytes belong to the agranulocyte class.
