## **Core Concept**
The question pertains to the characteristic histopathological findings in kidney diseases, specifically focusing on the pattern of fibrosis. Striped or band-like fibrosis in the kidney is associated with certain types of nephropathies.

## **Why the Correct Answer is Right**
The correct answer, **C. Analgesic nephropathy**, is associated with striped fibrosis of the kidney. Analgesic nephropathy, caused by long-term abuse of analgesics (especially phenacetin), leads to chronic interstitial nephritis and papillary necrosis. A hallmark histopathological feature of analgesic nephropathy is the presence of **striped fibrosis**, which refers to the band-like areas of fibrosis seen in the renal medulla and cortex.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because it does not correspond to a well-known cause of striped fibrosis in the kidney.
- **Option B:** This option is incorrect as it does not accurately represent a condition associated with striped renal fibrosis.
- **Option D:** This option is incorrect because it does not specify a condition known for causing striped fibrosis in the kidney.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that **analgesic nephropathy** is a preventable cause of chronic kidney disease, primarily due to the long-term use of certain over-the-counter pain medications. Patients with a history of analgesic abuse may present with renal failure, and imaging might show small, irregular kidneys. The condition is a classic example of a drug-induced kidney injury.

## **Correct Answer:** . Analgesic nephropathy
