Correct Answer correct answer
The correct answer is D) D and B

In patients with central DI, there is an inappropriately low secretion rate of ADH in response to changes in plasma osmolality, but there is no impairment in the renal response to ADH. Because plasma levels of ADH are depressed, there is an impaired ability to concentrate urine, and a large volume of dilute urine is excreted. Loss of water tends to increase plasma osmolality, which stimulates the thirst center. This leads to a very high rate of water turnover.
