Which of the following is a function of antidiuretic hormone (ADH)?

Explanation:
Antidiuretic hormone (ADH) regulates the body's water balance by acting on the kidneys. When ADH is present, it prompts the collecting ducts to reabsorb more water through aquaporin-2 channels, which makes the urine more concentrated and reduces its volume. This is why the function described as water reabsorption and urine concentration is correct. ADH does not increase urine volume, nor does it control blood glucose levels or trigger sweat production—the latter is governed by other systems and signals.
