Ethanol rendered unfit for use in intoxicating beverages by addition of other substances

• A. Dehydrated alcohol
• B. Denatured alcohol
• C. Rubbing alcohol
• D. Grain alcohol

Answer: (B)

Denatured alcohol is ethanol that has additives mixed in to make it unfit for human consumption while still serving as a useful solvent or fuel. The purpose of denaturing is exactly to prevent drinking, so the statement fits this term perfectly. Dehydrated alcohol is simply ethanol with the water removed and isn’t about making it undrinkable. Rubbing alcohol usually refers to isopropyl alcohol, not ethanol, and grain alcohol is pure, drinkable ethanol. Therefore, the described concept is denatured alcohol.
