Correct answer: B. contains ready made antibodies and gives only temporary protection
- A. contains weakened pathogens
- B. contains ready made antibodies and gives only temporary protection
- C. produces lifelong immunity
- D. stimulates the formation of memory cells
Explanation
Antiserum lends antibodies for immediate, short lived defence, while a vaccine teaches the body to make its own, lasting protection. Passive versus active is the distinction behind every option here.

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.
