Which of the following lists the correct energy density of alcohol and the implication for alcoholic beverages' caloric content?

Alcohol provides about 3 kcal/g, therefore alcoholic beverages are relatively low in calories and contribute little to daily energy intake.

Alcohol provides about 9 kcal/g, equal to fat, so alcoholic beverages always have the same caloric impact as high-fat foods per gram.

Alcohol provides zero usable kcal/g because the body cannot metabolize ethanol for energy, which is why beverages never appear on calorie counts.

Alcohol provides about 7 kcal/g, so alcoholic beverages can contribute substantial calories independent of macronutrient carbohydrates, proteins, or fats listed on some labels.
