Verified step by step guidance

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

Recognize the specific mechanisms by which antibodies function. Antibodies can neutralize pathogens by binding to them, preventing their entry into cells and marking them for destruction.

Differentiate between the options provided. Activation of the complement system and phagocytosis are processes that involve other components of the immune system, not directly the antibodies themselves.

Focus on the concept of neutralization. Neutralization is a direct action of antibodies where they bind to pathogens, blocking their ability to infect host cells.

Understand that the production of red blood cells is not related to antibody function. Red blood cell production is a separate physiological process not directly influenced by antibodies.
