Correct answer: D. B & T cells
- A. C-cells
- B. A & B cells
- C. B & C cells
- D. B & T cells
Explanation
The most abundant lymphocytes are B and T cells, which play critical roles in the immune system. B cells are responsible for producing antibodies, aiding in the identification and neutralization of pathogens. T cells have diverse roles, including attacking infected or cancerous cells and coordinating the immune response. Other options mention C-cells, which are not lymphocytes but rather thyroid cells, and A cells, which are not recognized in the context of lymphocytes.

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.
