Which of the following stimulates antibody production?

• A. Antigen
• B. Immunoglobulin
• C. T cell
• D. Plasma cell

Answer: (A)

Antigen triggers antibody production. In the humoral immune response, B cells have receptors that recognize a specific antigen. When a B cell binds its antigen, it internalizes and presents fragments to helper T cells, receiving signals that promote activation. With those signals, the B cell proliferates and differentiates into plasma cells that secrete antibodies tailored to that antigen. Immunoglobulin is the antibody itself, not what starts the process, while T cells help coordinate the response and plasma cells are the antibody factories. So the presence of an antigen is what initiates the production of antibodies.
