Which cells differentiate into plasma cells that produce antibodies?

• A. T lymphocytes
• B. B lymphocytes
• C. Dendritic cells
• D. Neutrophils

Answer: (B)

B lymphocytes differentiate into plasma cells that produce antibodies. These B cells originate in the bone marrow and, after recognizing their specific antigen and receiving help from helper T cells, they proliferate and specialize into plasma cells. Plasma cells become the primary secretors of antibodies, which circulate and target pathogens. Other cells mentioned have different roles: T lymphocytes mediate cell-based immunity and assist B cells but don’t become antibody factories; dendritic cells present antigens to T cells but don’t secrete antibodies; neutrophils are frontline phagocytes and do not produce antibodies.
