Final answer:
The only factor that can lower Blood Alcohol Concentration (BAC) is time, as only the liver can metabolize alcohol at a constant rate. Other methods like drinking water or eating won’t expedite this process.option a is correct answer.
Step-by-step explanation:
The only way to lower Blood Alcohol Concentration (BAC) is time. Alcohol is metabolized at a constant rate by the liver, and no other methods such as drinking water, consuming caffeine, or eating a heavy meal can speed up this process. It typically takes the liver about one hour to metabolize a standard drink, but this can vary depending on individual factors such as weight, age, and sex.
After reaching a legally intoxicated level of BAC (0.08), it takes at least five hours for a person to metabolize the alcohol and achieve sobriety.
Notably, drinking a large glass of water will increase urine output, which starts after about 30 minutes, but this does not affect BAC. Moreover, alcohol consumption leads to reduced production of antidiuretic hormone, causing increased urine production, but again this does not lower BAC.
