Option B) functions to increase sodium reabsorption.
Explanation:
Aldosterone is an hormone secreted by the cortex of the adrenal gland. The adrenal gland is situated at the superior poles of the right and left kidneys.
Aldosterone regulates sodium homeostasis and as such helps to control blood volume and blood pressure.
Aldosterone is secreted in response to decreased blood pressure (hypotension) to increase sodium reabsorption from urine, sweat, and the gut. Also excessive aldosterone levels (too high sodium) can lead to high blood pressure (hypertension).
