A patient has polyuria and polydipsia,and the urine osmolality is 100 mOsm/kg H₂O.The polyuria and polydipsia are not corrected by intravenous injection of ADH,and the exogenous ADH does not alter urine osmolality.What is the probable disorder in this patient?

A)SIADH
B)Osmotic diuresis
C)Central diabetes insipidus
D)Nephrogenic diabetes insipidus
E)Nephrolithiasis (renal stone)
