What is the primary type of alcohol found in all alcoholic beverages?

Ethyl alcohol, also known as ethanol, is the primary type of alcohol found in all alcoholic beverages. Ethanol is the only form of alcohol that is safe for human consumption when consumed in moderation. It is the active ingredient that produces the effects of intoxication and is responsible for the social and recreational use of alcoholic drinks.

Methyl alcohol, or methanol, is highly toxic and can cause serious health issues and death if ingested. Isopropyl alcohol, commonly found in rubbing alcohol, is also toxic and not safe for consumption. Butanol, while a type of alcohol, is less common in beverage production and is not suitable for drinking. Therefore, ethyl alcohol stands out as the sole type of alcohol that is consumed safely in beverages, making it the correct answer.
