Ans:
B

Feedback:

Increased sympathetic activity causes constriction of the afferent and efferent arterioles and thus a marked decrease in renal blood flow. Intense sympathetic stimulation can produce marked decreases in renal blood flow and GFR. Humoral substances, including angiotensin II, ADH, and endothelins, produce vasoconstriction of renal blood flow. Aquaporin-2 channels, potassium ions, and albumin do not have vasoconstriction properties.
