Vedclass · Answer

(C) An antigen is a molecule or molecular structure,such as may be present at the outside of a pathogen,that can be bound by an antigen-specific antibody or $B$-cell antigen receptor.Antigens are recognized by the immune system as foreign substances.When the immune system detects an antigen,it triggers the production of specific antibodies to neutralize or eliminate the pathogen.Therefore,an antigen acts as a stimulus for antibody production.
