Would Antibodies Produced by a Patient in Response to Infection

Would antibodies produced by a patient in response to infection be monoclonal,or polyclonal?

A) Since the infection is from only a single agent/microbe,the antibodies would be monoclonal.
B) Since a single pathogen has multiple antigens,and each antigen has multiple epitopes,the responding antibodies to a whole pathogen would be polyclonal.
C) Since the pathogen would most likely mutate slightly during the infection (producing different epitopes) ,the responding antibodies would be polyclonal.
D) Since the pathogen would acquire and modify self-antigens during the infectious process,the antibodies produced during the response would be polyclonal.
