A client is admitted to the hospital with a prerenal disorder, a nonurologic condition that disrupts renal blood flow to the nephrons, affecting their filtering ability. One cause of prerenal acute kidney injury is:

A. Polycystic disease is an intrinsic (renal) disorder affecting kidney tissue directly, not a prerenal cause. B. Anaphylactic shock causes severe hypotension, reducing renal perfusion, making it a prerenal cause of acute kidney injury. C. Ureteral stricture is a postrenal condition, causing obstruction to urine flow. D. Kidney stone is also a postrenal cause due to urinary tract obstruction.
