Although both vasopressin (ADH) and aldosterone significantly contribute to fluid and electrolyte balance, they do not appear to closely regulate blood volume in the long run. Blood volume is maintained at near normal levels in diabetes insipidus (absence of ADH) or Addison's disease (absence of aldosterone) because
(A) the peripheral renin-angiotensin system is stimulated
(B) salt and water intake are appropriately adjusted
© plasma oncotic pressure increases
(D) sympathetic reflexes decrease glomerular filtration
(E) renal blood flow decreases
