The answer is A. BAC is used to determine number of beverages consumed.
BAC is used to measure the level of intoxication of an individual. It is often expressed as the weight of ethanol in a given volume of blood. It must be noted that different people have different BACs due to several factors such as: weight, alcohol consumption, gender, and food intake. Though BAC is used to measure the amount of alcohol in the blood, it does not determine the number of beverages consumed.
