Which statement about a standard drink is accurate according to the material?

• A. A standard drink can be a 12-ounce beer
• B. A standard drink is always a 40-ounce beer
• C. A standard drink is a 6-ounce glass of wine
• D. A standard drink is a 2-ounce shot

Answer: (A)

A standard drink represents a fixed amount of pure alcohol, allowing you to compare servings across beverages. In the U.S., one standard drink is about 14 grams of alcohol, which roughly corresponds to 12 ounces of beer (about 5% ABV), 5 ounces of wine (about 12% ABV), or 1.5 ounces of 80-proof liquor. The statement that a 12-ounce beer is a standard drink fits this definition, so it’s accurate. The other options describe amounts that are either larger or smaller than one standard drink: a 40-ounce beer contains multiple standard drinks, a 6-ounce glass of wine is more than one standard drink, and a 2-ounce shot exceeds the standard 1.5-ounce shot.
