Helper T cells are responsible for activating B cells and initiating the humoral immune response. If stimulatory proteins are secreted, it indicates that helper T cells are functioning normally. Option A is related to the production of antibodies by activated B cells, which is a response of the humoral immune system. Option B is related to the generation of immunological memory, which occurs after both the primary and secondary immune responses, involving both B and T cells. Option D is related to the activation of the innate immune response, involving phagocytic cells, complement system, and cytokine signaling.
