Which cell type develops in the bone marrow and produces antibodies?

T Lymphocyte Macrophage Neutrophil B Lymphocyte

Correct Answer:

B Lymphocyte

Explanation:

B lymphocytes are responsible for antibody-mediated immunity. They develop in the bone marrow and, after activation by an antigen, differentiate into plasma cells that secrete antibodies. This antibody production is the hallmark of B cells. T lymphocytes mature in the thymus and handle cell-mediated responses, while macrophages and neutrophils are phagocytes and do not produce antibodies.
