dec pressure->inc renin->inc AT II -> inc aldosterone -> Na reabsorbtion -> C
Increase in arterial pressure will increases renal arterial blood pressure --> decrease in renin production and increase in Na excretion --> hypotension
So the answer is E.

in congestive heart failure there isn't a increase in arterial pressure! it's an increase in venous pressure, for the heart can't push it forward! It is well known that in CHF there is an activation of renin-angiotensin system that leads to an vicious circle that agravates the condition.. if there would be an increase in Na+ reabsorbtion, here wouldn't be any more cardiology residency positions and we would be unemplyed..

CCF -------------> Decrease in Effective Arterial blood volume(EABV) -----------> Activation of Baroreceptor -----------------> Increased sympathetic outflow from medulla vasomotor center -----------> Beta -1 stimulation of Juxtaglomerular cells -------------> increased renin production ---------> increased Angiotensin II -------------> Increased Aldosterone (secondary Hyperaldosteronism) --------------> Increased Na re-absorption
Best of luck
