Step-by-step solution

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.
