Correct Answer: A
Rationale: The correct answer is A: Aldosterone. Aldosterone is a mineralocorticoid produced by the adrenal cortex that specifically regulates salt and water balance in the body. It acts on the kidneys to increase the reabsorption of sodium and water, thus helping to maintain blood pressure and electrolyte balance.
Explanation for incorrect choices:
B: Glucagon - Glucagon is a hormone produced by the pancreas that primarily regulates blood sugar levels by promoting the release of glucose from the liver. It does not play a role in salt and water balance regulation.
C: Cortisol - Cortisol is a glucocorticoid that is involved in the body's response to stress and helps regulate metabolism, immune response, and inflammation. It does not have a direct role in salt and water balance.
D: ADH (antidiuretic hormone) - ADH is produced by the hypothalamus and acts on the kidneys to regulate water balance by increasing water reabsorption. While it is involved
