Correct option is (d) ADH
A decrease in blood pressure/volume stimulates the hypothalamus to release ADH (Antidiuretic Hormone) as well as JGA cells to release renin. Renin by renin angiotensin mechanism activates the adrenal cortex to release aldosterone. ANF (Atrial Natriuretic factor) is produced by atria of heart during increased blood pressure. It can cause vasodilation and thereby decrease the blood pressure.
