Option-B
Explanation:
ADH or antidiuretic hormone is a peptide hormone produced by the hypothalamus and released by the pituitary glands when the signals from the baroreceptors and the osmorecpetors act as a stimulus.
Under low or high-level condition these receptors transmit the signals and release the ADH.
This ADH after release binds to the collecting tubule in the kidney and promote the reabsorption of the water back in the tubule and thus increases the level of the water in the blood maintaining the osmolarity of plasma
Thus, Option-B is correct.
