**Core Concept**
Withdrawal seizures, particularly generalized tonic-clonic seizures (GTCs), are a complication of alcohol withdrawal in individuals with a history of chronic alcohol consumption. This condition is also known as Delirium Tremens (DTs).

**Why the Correct Answer is Right**
Benzodiazepines, such as Lorazepam, are the first-line treatment for managing seizures associated with alcohol withdrawal. They work by enhancing the effect of the neurotransmitter gamma-aminobutyric acid (GABA) at the GABA_A receptor, which has an inhibitory effect on neuronal activity. This action helps to reduce the excitability of neurons and prevent seizures. Lorazepam's pharmacokinetic profile, including its rapid onset of action and long duration of effect, makes it particularly suitable for managing acute seizures in this setting.

**Why Each Wrong Option is Incorrect**
* **Option A:** Phenobarbital is a barbiturate, which can exacerbate respiratory depression in patients with a history of chronic alcohol use. It is not the preferred choice for managing seizures in this context.
* **Option B:** Phenytoin is an antiepileptic medication, but it is not the first-line treatment for alcohol withdrawal seizures. It may be used in certain situations, but its use is generally reserved for patients with a history of epilepsy or those who have failed benzodiazepine treatment.

**Clinical Pearl / High-Yield Fact**
Benzodiazepines, particularly Lorazepam, are the cornerstone of treatment for alcohol withdrawal seizures due to their rapid onset of action, long duration of effect, and ability to reduce the risk of seizures. Always consider the patient's history of chronic alcohol use and the presence of withdrawal symptoms when selecting a treatment.

**Correct Answer:** C. Lorazepam.
