Select the correct statement

A Reduction in Glomerular Filtration Rate activates \(JG\) cells to release renin.
B Atrial Natriuretic Factor increases the blood pressure.
C Angiotensin \(II\) is a powerful vasodilator.
D Counter current pattern of blood flow is not observed in vasa recta.

Verified Solution

Answer & Solution

Correct Answer

(A) Reduction in Glomerular Filtration Rate activates \(JG\) cells to release renin.

Step-by-step Solution

Detailed explanation

The correct answer is option (1) because a fall in GFR/blood flow can activate the JG cells to release renin. Option (2) is incorrect statement as ANF causes vasodilation and thereby decrease the blood pressure.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
