Question

in the immune response,
o antibodies bind to antigens.
o pathogens engulf macrophages.
o helper t cells divide to produce plasma cells.
o lymphocytes invade the body.

Explanation:

In the immune response, antibodies (produced by B - cells) specifically bind to antigens (foreign substances). Macrophages engulf pathogens, not the other way around. Plasma cells are produced by B - cells, not helper T - cells. Lymphocytes are part of the immune system (not invaders).

Answer:

antibodies bind to antigens.
