a. Antibodies and antibiotics work the same way

b. Antibodies are chemicals that will kill pathogens

c. Antibodies will bind to the antigens and literally destroy the foreign organism

d. Antibodies will bind to the antigens and this complex will trigger opsonization

Answer 1

d. Antibodies will bind to the antigens and this complex will trigger opsonization

Opsonization is a term that refers to an immune process where particles such as bacteria or virus are targeted for destruction by an immune cell known as a phagocyte Opsonization involves the binding of an opsonin (e.g., antibody) to an epitope on a pathogen. (e.g, antigen) After opsonin binds to the membrane, phagocytes are attracted to the pathogen, antibody than binds to antigen

Epitope of pathogen could mean a piece of virus or bacteria, when a pathogen like bacteria or virus enters our blood stream, B lymphocytes are activated, which can bind to the virus and express the structure of virus on their surface, so that other cells like T lymphocytes can act on these virus particle and eliminate them.
