Which cell type is responsible for producing antibodies?

• A. B lymphocytes.
• B. T lymphocytes.
• C. Neurons.
• D. Erythrocytes.

Answer: (A)

B lymphocytes are responsible for producing antibodies. When a B cell encounters its specific antigen and receives help from other immune cells, it can differentiate into a plasma cell that secretes large amounts of antibodies. These antibodies circulate and bind to their targets, neutralizing pathogens or marking them for destruction by other parts of the immune system. T lymphocytes regulate the response and can kill infected cells but do not produce antibodies. Neurons are nerve cells and erythrocytes are red blood cells, neither of which makes antibodies.
