The ability of the immune system to mount a larger and more rapid response to an antigen that has already been encountered before is termed as:
Correct answer: B. Immunological Memory
- A. Primary Immune response
- B. Immunological Memory
- C. Short-term Memory
- D. Long-term Memory
Explanation
Memory cells formed during the first exposure allow a faster and larger secondary response when the same antigen returns, which is called immunological memory. The primary immune response is the slower first reaction, and short and long term memory are terms for brain function rather than immunity.

About Specific Defense Mechanism
Specific defense mechanisms provide targeted immunity through B lymphocytes, T lymphocytes, antibodies and memory cells that recognize particular antigens. Questions cover humoral and cell mediated responses, clonal selection, primary and secondary immune responses, vaccination and passive immunity, while distinguishing adaptive defenses from the immediate, non specific innate response.
