Which of the following does BAC not depend on?

• A. How fit you are
• B. How much you drank
• C. Time since you drank
• D. Your body weight

Answer: (A)

BAC reflects how much alcohol is in your bloodstream and how your body handles it. The amount you drink directly raises BAC because more alcohol enters your system. Time matters because your liver metabolizes alcohol gradually, so BAC falls as hours pass after drinking. Your body weight influences BAC because more body water to dilute the alcohol generally means a lower BAC for the same amount of drink. Fitness level, or how fit you are, doesn’t change how much you drink or how alcohol is distributed and processed in the body in a way that would alter BAC. So the factor that does not affect BAC is how fit you are.
