The correct sequence for the mammalian immune system's response to a pathogen starts with antigens from the pathogen binding to receptors on lymphocytes (III), followed by the proliferation of lymphocytes specific to the pathogen's antigens (IV), then these lymphocytes secrete antibodies (II), leading to the destruction of the pathogen (I), and finally, only memory cells remain (V) for a quicker response if the pathogen is encountered again.
