Assertion `:-` The amount of `CO_(20` that can diffuse through the diffusion membrane per unit differnece in partial pressure is much higher compared to that of `O_(2)`.
Reason `:-` The solubility of `CO_(20` is 20-25 times higher than that of `O_(20` solubility.

Options

A. If both Assertion & Reason are True & the Reasonn 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

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

### Step-by-Step Solution:

1. **Understanding the Assertion**:
The assertion states that the amount of CO2 that can diffuse through a diffusion membrane per unit difference in partial pressure is much higher compared to that of O2. This means that CO2 diffuses more readily than O2 across a membrane.

2. **Understanding the Reason**:
The reason given is that the solubility of CO2 is 20-25 times higher than that of O2. This implies that CO2 can dissolve in the blood more easily than O2, which facilitates its diffusion.

3. **Connecting Assertion and Reason**:
The reason explains why the assertion is true. Since CO2 is much more soluble than O2, it can diffuse more effectively across the diffusion membrane (like the alveolar-capillary membrane in the lungs).

4. **Conclusion**:
Both the assertion and the reason are true, and the reason provides a correct explanation for the assertion. Therefore, the answer to the question is that both the assertion and the reason are true, and the reason is the correct explanation for the assertion.

### Final Answer:
Both assertion and reason are true, and the reason is the correct explanation for the assertion.
