Accepted Answer

A) Naive pathogen-specific B cells are suppressed by negative signaling through FcγRIIB1. 
B) Naive pathogen-specific B cells isotype switch and hypermutate much more quickly during secondary immune responses. 
C) Memory B cells outnumber naive B cells. 
D) Low-affinity IgM antibodies are made only when antigen concentration is exceedingly high.
