Which statement best describes the difference between responses of effector B cells (plasma cells) and those of cytotoxic T cells? (A) B cells confer active immunity;cytotoxic T cells confer passive immunity. (B) B cells respond the first time a pathogen is present; cytotoxic T cells respond subsequent times.
