Answer: D

Reasoning: 
• Peripheral eosinophilia is a classic clue to drug-induced acute interstitial nephritis [McMenamin, 1976, PMID 139882].  
• It is also present in most cases of atheroembolic (cholesterol) renal disease, being reported in ≈80 % of patients with biopsy-proven disease [Kasinath, 1987, PMID 3631147].  
• In polyarteritis nodosa, renal involvement is common but peripheral eosinophilia is uncommon (seen in only about 20 % of cases in clinical series) [Kirkland, 1997, PMID 9105764].  

Thus, the combination of renal failure with peripheral eosinophilia is least likely in polyarteritis nodosa.
