The correct option is D Renin
Rennin is a hormone secreted by kidney and serves to stimulate secretion of aldosterone from adrenal cortex and serve in regulation of blood pressure. Renin also serves as an enzyme and converts the plasma protein angiotensinogen to angiotensin I, which is converted in to angiotensin II. The enzyme acetylcholinesterase inactivates excess acetylcholine into its chemical components acetic acid and choline. ADH is hormone that regulates water reabsorption. Thus, the correct answer is option D.
