AIIMS 2019 Zoology Immune Tolerance MCQ Question

Immunity tolerance is primarily developed through the interaction with antigens, where the immune system learns to recognize self-antigens and refrain from mounting an immune response against them. This process is crucial for preventing autoimmune diseases. Option B is incorrect because giving antibodies does not induce tolerance; rather, it provides passive immunity. Option C is misleading, as while some tolerance mechanisms can be innate, most are acquired through exposure to antigens. Option D is irrelevant, as antibiotics target bacteria and do not influence the immune tolerance process.
