Ethanol's safe usage can be attributed to its metabolic pathway and the presence of its effects when consumed in moderation. Understanding the difference between these two types of alcohol is crucial in the bartending field, as the safe handling of ethanol for drink preparation is fundamental, while methanol poses significant dangers if ingested.

The other pairs mentioned do include types of alcohol, but they are not the primary categories relevant to consumption and beverage preparation. Isopropanol is commonly used as a disinfectant and cleaning agent, but like methanol, it is not safe to drink. Butanol is an alcohol primarily utilized in industrial applications. Ethylene, although a gas related to plant hormones, is not classified as an alcohol suitable for consumption. Thus, recognizing ethanol as the safe alcohol for beverages and
