________ immunity is developed after overcoming a disease, through inoculation or through exposure to natural allergens.

• A. Acquired
• B. Natural
• C. Passive
• D. Innate

Answer: (A)

Acquired immunity develops after your body encounters a pathogen or receives a vaccine, and it’s highly specific and long-lasting because it builds memory through B and T lymphocytes. After overcoming a disease or being inoculated, your immune system learns to recognize that specific antigen, so future exposures trigger a faster, stronger response. This contrasts with innate (natural) immunity, which is your built-in, non-specific defense present from birth and doesn’t create lasting antigen-specific memory. It also differs from passive immunity, where protection comes from antibodies made by another person or animal and is temporary. The description in the question aligns with the adaptive, acquired type of immunity.
