Antidiuretic hormone (ADH) or vasopressin facilitates the reabsorption of water from the latter parts of the tubule (DCT and collecting duct), thereby preventing diuresis.

Deficiency of ADH leads to a decrease in water reabsorption, which results in the production of a large volume of dilute urine. This condition is known as Diabetes insipidus.

Due to the excessive loss of water through urine (polyuria), the person experiences increased thirst (polydipsia) to compensate for the fluid loss.

Therefore, concentrated urine is not produced during ADH deficiency; instead, the urine is highly dilute.

Answer: Concentrated urine is produced
