The correct answer is option 3 - antigen. An antigen is a substance that triggers an immune response in a living organism, leading to the production of antibodies. Antibodies are proteins produced by the immune system to help recognize and neutralize foreign substances such as bacteria, viruses, and toxins. When an antigen enters the body, it stimulates the immune system to produce specific antibodies that can bind to and target the antigen for destruction. This immune response is important for fighting infections and providing immunity against future exposure to the same antigen. Carcinogen, androgen, and estrogen are unrelated to the production of antibodies and do not have the same role in the immune system.
