• D. Benzodiazepines

Answer: (C)

Delirium tremens is the severe withdrawal state that can occur after heavy, prolonged alcohol use when drinking stops or is reduced. It typically begins within 48 to 72 hours after the last drink and features delirium (confusion and disorientation) along with tremors, agitation, and marked autonomic signs like rapid heart rate, high blood pressure, sweating, and fever. Visual or tactile hallucinations are common as well. Because of the potential for serious complications such as seizures, dehydration, and cardiovascular instability, it requires urgent medical attention and is often managed in a hospital setting with careful withdrawal management and supportive care. This syndrome is specifically associated with alcohol withdrawal; withdrawal from other substances—opioids, cannabis, or benzodiazepines—produces different symptom patterns and timing.
