Reason: ANF mechanism is one such efficient mechanism.

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 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 kidneys have built-in mechanisms for the regulation of glomerular filtration rate (GFR)." - This is true. The kidneys do have mechanisms to regulate GFR, which is crucial for maintaining homeostasis in the body. 2. **Understanding the Reason**: - The reason states that "ANF mechanism is one such efficient mechanism." - Atrial Natriuretic Factor (ANF) is indeed involved in the regulation of blood pressure and fluid balance, but it acts antagonistically to the mechanisms that increase GFR, such as the Renin-Angiotensin-Aldosterone System (RAAS). 3. **Evaluating the Relationship**: - While both the assertion and the reason are true statements, the reason does not correctly explain the assertion. ANF is not a mechanism that increases GFR; rather, it works to decrease blood pressure and inhibit renin secretion, which can lead to a decrease in GFR. 4. **Conclusion**: - Since the assertion is true and the reason is false, the correct answer is that the assertion is true but the reason is false. ### Final Answer: The correct option is: **Third option - Assertion is true but reason is false.** ---
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 kidneys have built-in mechanisms for the regulation of glomerular filtration rate (GFR)." - This is true.
