Assertion`:` Myoglobin shows more affinity for the `O_(2)` as compared to Haemoglobin
Reason `:-` It is also found in red fibres of voluntary muscle.

Options

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

Answer

### Step-by-Step Solution

1. **Understanding Myoglobin and Hemoglobin**:
- Myoglobin is a protein found in muscle tissues that binds oxygen. It has a higher affinity for oxygen compared to hemoglobin, which is found in red blood cells and carries oxygen throughout the bloodstream.

2. **Analyzing the Assertion**:
- The assertion states that "Myoglobin shows more affinity for the O₂ as compared to Hemoglobin." This is true. Myoglobin's structure allows it to hold onto oxygen more tightly, which is essential for muscle function, especially during intense exercise.

3. **Analyzing the Reason**:
- The reason provided states that "It is also found in red fibers of voluntary muscle." This is also true. Myoglobin is abundant in red muscle fibers, which are responsible for endurance and sustained activities.

4. **Evaluating the Relationship**:
- While both the assertion and the reason are true, the reason does not explain why myoglobin has a higher affinity for oxygen. The higher affinity is due to its molecular structure and function, not merely its presence in red muscle fibers.

5. **Conclusion**:
- Therefore, both the assertion and the reason are true, but the reason is not the correct explanation for the assertion. The correct answer is that the assertion is true, and the reason is true but does not explain the assertion.

### Final Answer:
Both assertion and reason are true, but the reason is not the correct explanation for the assertion.
