B cells are important immune cells that fight infections. How is a naïve B cell stimulated to mature into a plasma cell that secretes antibodies? a. T cells secrete cytokines, which help the B cell to multiply and mature into an antibodyproducing plasma cell. b. Natural killer cells secrete cytokines, which help the B cell to multiply and mature into an antibody-producing plasma cell. c. T cells secrete interferons, which help the B cell to multiply and mature into an antibodyproducing plasma cell. d. Natural killer cells secrete interferons, which help the B cell to multiply and mature into an antibody-producing plasma cell.
