Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of immunology terminology.
Step 2: Detailed Explanation:
An antigen is a substance that, when injected into the body, evokes the production of antibodies.
It is recognized by the immune system as foreign.
Hapten (A): A small molecule that can bind to antibodies but cannot evoke immune response alone (needs carrier).
Antibody (B): The protein produced in response to antigen.
Serum (C): Blood plasma without clotting factors.
Thus, an antigen evokes antibody production.
Step 3: Final Answer:
Thus, an antigen evokes antibody production, which corresponds to option (D).

- Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): The disruption of $\beta$-oxidation of fatty acids in plants can potentially reduce stress-induced ROS accumulation and improve its stress tolerance.
Reason (R): In plants, $\beta$-oxidation of fatty acids takes place predominantly in peroxisomes, where first enzyme of $\beta$-oxidation viz. fatty acyl CoA oxidase produces large amounts of hydrogen peroxide.
