What type of immunity do antibodies primarily provide?

• A. Innate immunity
• B. Passive immunity
• C. Adaptive immunity
• D. Non-specific immunity

Answer: (C)

Antibodies primarily provide adaptive immunity, which is a specific and targeted response to pathogens. This type of immunity develops over time and is characterized by the ability to recognize and remember specific antigens, leading to a stronger and quicker response upon subsequent exposures to the same pathogen. Adaptive immunity involves the activation of lymphocytes, specifically B cells, which are responsible for producing antibodies. These antibodies bind to specific antigens on pathogens, neutralizing them or marking them for destruction by other immune cells. This targeted nature distinguishes adaptive immunity from innate immunity, which is a general and immediate response to a wide range of pathogens without specificity. Unlike passive immunity, which involves the transfer of antibodies from one individual to another (such as maternal antibodies passed to an infant), adaptive immunity is generated by the individual's own immune system through exposure to antigens, whether from infections or vaccinations. Non-specific immunity refers to the general defenses against infection that do not depend on the presence of specific pathogens, which further highlights the distinct role of adaptive immunity where antibodies are tailored to specific threats. Thus, the provision of antibodies falls squarely within the realm of adaptive immunity.
