Solution
The correct option is C Angiotensin II and Aldosterone
Rabbits are herbivores and thus the urine is normally alkaline (pH 8-9) and turbid. The regulatory activities of kidneys lead to the formation of urine as a by-product. Urine formation involves three main steps—the glomerular filtration, the tubular reabsorption, and the tubular secretion. To keep the sodium and water balance in check, the angiotensin and aldosterone system helps. The inactive angiotensinogen is converted to angiotensin I which is then converted to angiotensin II. This along with aldosterone helps in maintaining the required amount of sodium and water along with re-absorption of salts.
