<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:Ten days after being discharged from the hospital, a 42-year-old man comes to the emergency department because of reduced urine output for 3 days. Physical examination is normal. Serum creatinine concentration is 2.9 mgdL. Urinalysis shows brownish granular casts and 2 proteinuria. Renal biopsy shows patchy necrosis of the proximal convoluted tubule with sloughing of tubular cells into the lumen and preservation of tubular basement membranes. Administration of which of the following drugs during this patients hospitalization is most likely the cause of the observed decrease in renal function?? A: Captopril, B: Aspirin, C: Acyclovir, D: Omeprazole, E: Gentamicin,  <response>: This is a question about drug-induced acute kidney injury. The key finding in the question stem is patchy necrosis of the proximal convoluted tubule on renal biopsy, which indicates acute tubular necrosis ATN. The patients history of recent hospitalization and new onset reduced urine output suggests this is acute kidney injury rather than chronic kidney disease. The timeline of 10 days after discharge also suggests this acute kidney injury is related to a medication given during the recent hospitalization.Of the answer choices, gentamicin is an aminoglycoside antibiotic that is well known to cause proximal tubular toxicity and acute tubular necrosis. The other answer choices are less likely to cause this type of kidney injury.E: Gentamicin
