The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step 1: Analyze the Assertion The assertion states that "100 ml of venous blood carries 4 ml of CO2 to the alveoli under normal physiological conditions." - In normal physiological conditions, venous blood does indeed carry carbon dioxide (CO2) from the tissues back to the lungs for exhalation. - It is known that approximately 4 ml of CO2 can be carried in 100 ml of venous blood. This is a true statement. ### Step 2: Analyze the Reason The reason states that "About 5 ml of O2 diffuses from arterial blood into the tissue during normal conditions." - Under normal physiological conditions, oxygen (O2) is transported from the arterial blood to the tissues. - It is true that approximately 5 ml of O2 diffuses from arterial blood into the tissues per 100 ml of blood. This statement is also true. ### Step 3: Determine the Relationship Now we need to determine if the reason provided is a correct explanation for the assertion. - The assertion is about the transport of carbon dioxide in venous blood, while the reason is about the transport of oxygen in arterial blood. - Although both statements are true, they are not directly related to each other. The amount of CO2 carried in venous blood does not depend on the amount of O2 that diffuses into tissues. ### Conclusion - The assertion is true. - The reason is true, but it does not explain the assertion. - Therefore, the correct answer is that the assertion is true, and the reason is true but not the correct explanation for the assertion. ### Final Answer The correct option is that the assertion is true, and the reason is true but not the correct explanation. ---
