An Antigen-Antibody Complex _______

Question

An antigen-antibody complex _______.
A) attacks mast cells
B) stimulates phagocytes to destroy pathogens
C) presents antigens to plasma cells

Accepted Answer

This is an important mechanism for the immune system to eliminate pathogens. None of the other choices are accurate descriptions of the role of antigen-antibody complexes in the immune response.
