BSame
CNo effect
DLESS urine — water retained, urine concentrated
Answer & Solution
Correct answer: D. LESS urine — water retained, urine concentrated
ADH = antidiuretic (anti-urine) hormone.
Promotes water reabsorption → concentrated low-volume urine.
Diabetes insipidus = ADH deficiency → polyuria (large dilute urine).
Diuretics (e.g., furosemide, alcohol) increase urine output by various mechanisms.
