**Core Concept**
Interstitial nephritis is a type of kidney inflammation that affects the spaces between the renal tubules, often caused by immune-mediated reactions or toxic substances. This condition can lead to impaired kidney function and is commonly associated with various medications, infections, and autoimmune diseases.

**Why the Correct Answer is Right**
The correct answer is related to the fact that certain drugs can induce interstitial nephritis due to their toxic effects on the renal tubules. Nonsteroidal anti-inflammatory drugs (NSAIDs) are a common cause of this condition, as they can cause direct damage to the renal tubular cells. This damage triggers an immune response, leading to inflammation and interstitial nephritis.

**Option B:** This option is also not provided, so we cannot evaluate its correctness.

**Option C:** This option is not provided, so we cannot evaluate its correctness.

**Clinical Pearl / High-Yield Fact**
A classic exam trap is to confuse NSAIDs with other classes of drugs that are not typically associated with interstitial nephritis. For example, penicillin and other antibiotics can cause allergic interstitial nephritis, but this is a distinct entity from the NSAID-induced form.
