Verified step by step guidance

Step 1: Understand the concept of agranulocytes. Agranulocytes are a type of white blood cell that lack visible granules in their cytoplasm. They play a crucial role in the immune system and include lymphocytes and monocytes.

Step 2: Learn about the two types of lymphocytes: B lymphocytes and T lymphocytes. B lymphocytes are primarily responsible for antibody-mediated (humoral) immunity, while T lymphocytes are involved in cell-mediated immunity.

Step 3: Recall the function of B lymphocytes. These cells produce antibodies that bind to specific antigens, marking them for destruction or neutralization. This process is central to humoral immunity.

Step 4: Eliminate incorrect options. Monocytes are agranulocytes but are involved in phagocytosis and not antibody production. Neutrophils are granulocytes and are also involved in phagocytosis, not humoral immunity. T lymphocytes are responsible for cell-mediated immunity, not antibody production.

Step 5: Conclude that the correct answer is B lymphocyte, as it is the agranulocyte responsible for antibody-mediated (humoral) immunity.
