Answer:

b. Aldosterone promotes sodium reabsorption in the kidneys.

Explanation:

Once it is produced by the adrenal gland it stimulates the mineralocorticoid receptors on the distal tubule and collecting duct of the kidney's nephrons. This causes sodium reabsorption in the kidneys indirectly affecting water retention.
