Which of the following does not favour the formation of large quantities of dilute urine?

Renin does not favour the formation of large quantities of dilute urine. Renin helps to raise the circulating blood volume and in turn, blood pressure. It also increases the secretion of ADH from the posterior pituitary gland - resulting in the production of more concentrated urine to reduce the loss of fluid from urination.Atrial-natriuretic factor increases the excretion of water and sodium.Alcohol and Caffeine are also diuretics (inhibit ADH) which also favour the formation of large amounts of urine.
