Assertion : ELISA test is based on antigen-antibody interactions where a pathogen can be detected by the presence of antibodies (proteins,glycoproteins, etc) on it
Reason : The pathogen antibody to be identified is immobilised on the surface of specially constructed ELISA plates and is then tested.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but reason is false

D

If both assertion and reason are false

The correct Answer is:
To analyze the given assertion and reason regarding the ELISA test, we will break down the statements step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that the ELISA test is based on antigen-antibody interactions, where a pathogen can be detected by the presence of antibodies on it. - **Clarification**: In ELISA, it is actually the antigens (not antibodies) present on the pathogen that are detected by specific antibodies. Thus, the assertion is misleading. 2. **Understanding the Reason**: - The reason states that the pathogen antibody to be identified is immobilized on the surface of specially constructed ELISA plates and then tested. - **Clarification**: In ELISA, it is the antigens from the pathogen that are immobilized on the ELISA plates, not the antibodies. The antibodies are added later to detect these antigens. Therefore, this statement is also incorrect. 3. **Conclusion**: - Both the assertion and the reason are incorrect. The assertion incorrectly describes the role of antibodies and antigens, and the reason incorrectly describes what is immobilized on the ELISA plates. 4. **Final Answer**: - Since both the assertion and reason are false, the correct answer is option 4.
