The body generally processes alcohol at a rate of about one standard drink per hour. A standard drink is typically defined as containing approximately 14 grams of pure alcohol, which is found in: - 12 ounces of beer (with about 5% alcohol content) - 5 ounces of wine (with about 12% alcohol content) - 1.5 ounces of distilled spirits (with about 40% alcohol content) If a person has consumed four standard drinks, it would take roughly four hours for the body to eliminate all of the alcohol from those drinks. This is based on the average metabolism of alcohol, which can vary depending on factors such as individual health, weight, and drinking habits, but four hours is a generally accepted benchmark for this quantity of alcohol. Therefore, the correct answer is that the body takes about four hours to eliminate alcohol from four drinks.
