The correct answer is option (4) because,
• Diuresis is prevented by vasopressin or anti-diuretic hormone from neurohypophysis or posterior pituitary. When there is excessive loss of fluid from the body the secretion of, ADH facilitates water reabsorption from latter part of renal tubules.
• Option (1) is incorrect because renin from JG cells convert angiotensinogen in blood to angiotensin I and further to angiotensin II; which is a powerful vasoconstrictor and increases the glomerular blood pressure and thereby GFR.
• Option (2) is incorrect because ANF causes vasodilation and thereby decrease GFR.
• Option (3) is incorrect because aldosterone is released from adrenal cortex and causes reabsorption of
Na+ and water from distal parts of renal tubules.
