Assertion: For effective treatement of a disease, early dignosis & understanding its pathophysiology is very important
Reason :r-DNA technique, PCR & ELISA serve the purpose of early diagnosis

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion
B. It both Assertion & Reason are True but Reason is not a correct explanation of the Assetion
C. If Assertion is True but the Reason is False
D. If both Assertion & Reason are false

Answer

To solve the question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "For effective treatment of a disease, early diagnosis & understanding its pathophysiology is very important."
- This is true because early diagnosis allows for timely intervention, which can lead to better treatment outcomes. Understanding the pathophysiology helps in identifying the underlying mechanisms of the disease, which is crucial for effective treatment.

2. **Understanding the Reason**:
- The reason states that "r-DNA technique, PCR & ELISA serve the purpose of early diagnosis."
- This is also true. Recombinant DNA (r-DNA) technology, Polymerase Chain Reaction (PCR), and Enzyme-Linked Immunosorbent Assay (ELISA) are all techniques used in modern diagnostics to detect diseases early.
- r-DNA technology can help identify genetic disorders, PCR can amplify specific DNA sequences to detect pathogens, and ELISA is commonly used for detecting antibodies or antigens in various diseases.

3. **Analyzing the Relationship**:
- The assertion emphasizes the importance of early diagnosis and understanding pathophysiology for effective treatment.
- The reason provides examples of techniques that facilitate early diagnosis.
- Since both the assertion and the reason are true, and the reason explains how early diagnosis can be achieved, we conclude that the reason is a correct explanation of the assertion.

4. **Conclusion**:
- Both the assertion and the reason are true, and the reason correctly explains the assertion. Therefore, the correct answer is that both are true and the reason is a correct explanation of the assertion.

### Final Answer:
- Option A: Both assertion and reason are true, and reason is a correct explanation of the assertion.
