Assertion (A): Patients suffering from Diabetes mellitus and Diabetes insipidus both exhibit significant loss of water through urine. Reason (R): Insulin is secreted by the -cells of the pancreas, whereas ADH is synthesised by the hypothalamus. In the light of the above statements, choose the most appropriate ans
