Complement-fixing antibodies are those that function by:
a. attaching to the surface of pathogens and contributing to their destruction by the lytic action of complement.
b. binding to and blocking surface receptors for host cells.
c. attaching to the surface of pathogens and making the pathogens more amenable to ingestion by phagocytic cells.
d. attaching to the surface of pathogens and contributing to their destruction by che-motaxis.
A
Antibodies function in different ways. Complement-fixing antibodies work by attaching to the surface of pathogens and contributing to their destruction by the lytic action of complement.
