**Core Concept**
The nephrotoxicity of certain substances is a significant concern in clinical practice, as it can lead to acute kidney injury (AKI) or chronic kidney disease (CKD). Nephrotoxicity can result from direct damage to renal cells, vasoconstriction of renal blood vessels, or disruption of normal renal function.

**Why the Correct Answer is Right**
Amphotericin B is an antifungal medication that is known to cause nephrotoxicity as a side effect. This is due to its ability to bind to cholesterol in the renal cell membranes, leading to cell lysis and disruption of normal renal function. The resulting inflammation and fibrosis can cause a decrease in renal function, making it a significant concern in patients with pre-existing kidney disease. The nephrotoxic effects of amphotericin B are dose-dependent and can be mitigated by administering it in conjunction with other medications, such as sodium supplementation.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not provided, but for the sake of explanation, if it were a non-nephrotoxic medication, it would be incorrect because it does not have known nephrotoxic effects.
* **Option B:** This option is not provided, but for the sake of explanation, if it were a medication that is not known to cause nephrotoxicity, it would be incorrect because it does not have known renal toxicity.
* **Option C:** This option is not provided, but for the sake of explanation, if it were a medication that is known to cause nephrotoxicity, it would be incorrect because it is not the correct answer being sought.
* **Option D:** This option is not provided, but for the sake of explanation, if it were a non-nephrotoxic medication, it would be incorrect because it does not have known nephrotoxic effects.

**Clinical Pearl / High-Yield Fact**
Amphotericin B-induced nephrotoxicity can be decreased by administering it in conjunction with sodium supplementation, which helps to maintain normal renal function. Additionally, monitoring renal function closely and adjusting the dosage of amphotericin B as needed can also help to mitigate its nephrotoxic effects.

**Correct Answer:** C.
