Step-by-step explanation:
A. Blood alcohol concentration is affected by factors such as body size and gender.
Blood alcohol concentration (BAC) refers to the amount of alcohol present in a person's bloodstream. It is influenced by various factors, including body size, weight, gender, metabolism, the rate of alcohol consumption, and the presence of food in the stomach. Factors such as a smaller body size, lower body weight, and female gender tend to result in a higher BAC compared to larger body size, higher body weight, and male gender when consuming the same amount of alcohol.
