B)presentation of MHC-antigen complex on a cell surface

Activation of the adaptive immune response requires presentation of the MHC-antigen complex on a cell surface. This allows for recognition by T cells, which then initiate the adaptive immune response. Memory cells, somatic hypermutation, and phagocytosis of antibody-antigen complex by macrophages are all part of the adaptive immune response, but they are not crucial to its activation.
