## Core Concept
The question pertains to the management of opioid dependence, specifically heroin detoxification. Various pharmacological agents are utilized in the treatment of opioid withdrawal and dependence.

## Why the Correct Answer is Right
Buprenorphine is a partial opioid agonist at the mu-opioid receptor and is used for opioid substitution therapy, helping to manage withdrawal symptoms and cravings. Methadone is a long-acting opioid agonist that also helps in reducing withdrawal symptoms. Clonidine, an alpha-2 adrenergic agonist, can alleviate some symptoms of opioid withdrawal but is not primarily used for long-term management. Naltrexone, an opioid antagonist, is used to prevent relapse by blocking the euphoric effects of opioids but is not used for detoxification.

## Why Each Wrong Option is Incorrect
* **Option A:** Buprenorphine is indeed used for heroin detoxification as it helps manage withdrawal symptoms.
* **Option B:** Methadone is used for opioid substitution therapy and helps in detoxification.
* **Option C:** Clonidine can be used to manage some symptoms of opioid withdrawal.

## Clinical Pearl / High-Yield Fact
A key point to remember is that while Naltrexone is crucial in the management of opioid dependence, particularly in preventing relapse, it does not alleviate withdrawal symptoms and thus is not used for detoxification.

## Correct Answer: D. Naltrexone
