If you look at the answer correctly you would see that it would be C
Out of the following
A. .08 BAL per hour
B. .05 BAL per hour
C. .018 BAL per hour
D. .015 BAL per hour
The answer is D. This is equivalent to 0.015 g / 100mL / hour leaving your body after alcohol intake. This occurs after the alcohol is broken down by the liver to acetaldehyde and then to acetic acid by alcohol dehydrogenase (ADH). The acetic acid is later excreted through the kidneys and skin. On average, the liver can metabolize 1 ounce of alcohol every hour. It takes approximately 5.5 hours for 0.08 ounces of alcohol to leave the system after intake.
