Verified step by step guidance

Understand the role of antibodies in the immune response: Antibodies are proteins produced by the immune system to identify and neutralize foreign objects like bacteria and viruses.

Review the possible outcomes of an antigen-antibody reaction: These include activation of the complement system, neutralization of the antigen, and opsonization to enhance phagocytosis.

Analyze each option: Activation of the complement system involves a series of proteins that assist in destroying pathogens. Neutralization involves antibodies binding to antigens to block their harmful effects. Opsonization involves marking pathogens for destruction by phagocytes.

Consider the mechanism of direct destruction: Antibodies themselves do not directly destroy antigens. Instead, they mark them for destruction by other components of the immune system.

Identify the statement that does not align with the known functions of antibodies: Since antibodies do not directly destroy antigens, this statement is the one that is NOT a possible outcome of an antigen-antibody reaction.
