What type of drug is alcohol classified as?

Answer: C — central nervous system depressant

Alcohol is classified as a central nervous system depressant because it slows down brain activity and suppresses the central nervous system. It is not a stimulant because it does not increase activity or alertness. It is not a hallucinogen because it does not cause hallucinations or distort perception. It is also not an antibiotic because it does not treat bacterial infections. Therefore, option C is the correct classification for alcohol.
