## Core Concept
Ethylene glycol poisoning is a serious condition that requires prompt treatment. The primary goal of treatment is to inhibit the metabolism of ethylene glycol to its toxic metabolites. This is achieved through the administration of specific antidotes.

## Why the Correct Answer is Right
The correct answer, **C. Fomepizole**, is a potent inhibitor of alcohol dehydrogenase, the enzyme responsible for converting ethylene glycol into its toxic metabolites, such as glycolaldehyde and oxalic acid. By inhibiting this enzyme, fomepizole effectively reduces the formation of these toxic compounds, thereby mitigating the severity of ethylene glycol poisoning. Fomepizole is a specific and effective antidote for ethylene glycol and methanol poisoning.

## Why Each Wrong Option is Incorrect
- **Option A:** This option is incorrect because it is not specified, making it impossible to evaluate its accuracy.
- **Option B:** This option is incorrect because it is not specified, making it impossible to evaluate its accuracy.
- **Option D:** This option is incorrect because it is not specified, making it impossible to evaluate its accuracy.

## Clinical Pearl / High-Yield Fact
A key clinical pearl is that fomepizole is a more specific and safer alternative to ethanol, which has historically been used to treat ethylene glycol poisoning. Fomepizole does not require close monitoring of blood levels and has fewer side effects compared to ethanol.

## Correct Answer: C. Fomepizole.
