After attachment to host cells, a pathogen may use the following mechanisms to establish itself and cause disease, except:
A) Uses lactoferrin for iron
B) Produces an IgA protease that degrades the IgA at mucosal surfaces
C) Produces lysozyme to kill the host cell
D) Circumvents host antibodies by shifting key cell-surface antigens
