What is the function of an antigen in an antigen-antibody response? a. inform white blood cells of the invader so it can be destroyed b. is informed by the white blood cell of an invader so it can be destroyed c. restore dna in damaged cells d. provide a protective shell around the antibody

A) inform the white blood cells of the invader so it can be destroyed. This works because antigens are proteins, and proteins have unique complex structures; the combination of antigens on the surface of a pathogen will each cause an immune response in the body, and ultimately white blood cells are part the immune system responses to destroy this pathogen.
