**Core Concept**
The question is testing the pharmacological treatment of nicotine addiction, specifically the use of medications for smoking cessation. The correct answer will involve a medication that targets the nicotinic acetylcholine receptors in the brain.

**Why the Correct Answer is Right**
The correct answer is a medication that acts as a nicotinic receptor antagonist, reducing the pleasure and reward associated with smoking. This medication works by blocking the action of nicotine at its receptor sites in the brain, thereby reducing the craving for cigarettes. The medication is often used in combination with counseling and behavioral therapy to increase its effectiveness.

**Option C:** This option is incorrect because it is a medication used to treat hypertension and not nicotine addiction.

**Clinical Pearl / High-Yield Fact**
One high-yield fact to remember is that the medications used for smoking cessation, including the correct answer, are most effective when used in combination with counseling and behavioral therapy. This approach can increase the chances of successful smoking cessation by addressing both the physical and psychological aspects of nicotine addiction.
