Which of the following does not favor the formation of large quantities of dilute urine?
  1. Alcohol
  2. Caffeine
  3. Renin
  4. Atrial - natriuretic factor

Renin does not favor for the formation of large quantities of dilute urine as it activates RAAS (Renin-angiotensin activating system), so it causes reabsorption of sodium which leads to the formation of concentrated urine.
