The role of antibodies in the human body is to

1. stimulate pathogen reproduction to produce additional white blood cells
2. increase the production of guard cells to defend against pathogens
3. promote the production of antigens to stimulate an immune response
4. recognize foreign antigens and mark them for destruction



Answer :

Final answer:

Antibodies in the human body recognize foreign antigens and mark them for destruction.


Explanation:

Antibodies play a crucial role in the human body by recognizing foreign antigens and marking them for destruction. When activated B cells encounter antigens, they produce antibodies that specifically bind to the antigen to combat the infection. These antibodies can promote opsonization, coat pathogens, and stimulate the complement cascade for pathogen destruction.
