Question

Assertion (A): Innate immunity includes built-in molecular and cellular mechanisms that are encoded in the germline and are evolutionarily more primitive. Reason (R): Immune responses by B and T lymphocytes are much more attuned to subtle molecular differences and more antigen-specific.

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A).
• B. Both (A) and (R) are correct but (R) is NOT the correct explanation of (A).
• C. (A) is correct but (R) is not correct.
• D. (A) is not correct but (R) is correct.
