Immunity Type Source A. Innate Immunity 1. Natural infection B. Acquired Immunity 2. Colostrum C. Active Immunity 3. Interferons D. Passive Immunity 4. Antibodies

Step-by-step solution

Innate immunity includes non-specific defense mechanisms like interferons that provide immediate protection against a wide range of pathogens. Acquired immunity is developed through exposure to specific pathogens, resulting in the production of antibodies by the immune system. Active immunity is acquired through natural infection or vaccination, where the immune system actively produces its own antibodies and memory cells. Passive immunity is provided by transferring antibodies from another source, such as through
