A common strategy by which microbes survive their host’s immune responses involves changing the structures of the molecules they produce so that they are no longer recognized by the host’s immune system. This strategy, called antigenic variation, is most likely to allow evasion of which type of immune recognition? Group of answer choicesa. Natural killer cell inhibitory receptor recognition of class I major histocompatibility complex (MHC) molecules on infected cellsb. Antibody recognition of microbial cell surface moleculesc. Toll-like receptor–dependent recognition of microbes by cells of the innate immune systemd. T cell receptor (gamma/delta) recognition of microbial cell wall lipid antigense. Mannose receptor–dependent recognition of microbes by cells of the innate immune system
