The correct response to the question is that only the liver can eliminate alcohol from the body. This is based on a fundamental understanding of how the human body processes alcohol. The liver is responsible for metabolizing alcohol, breaking it down into less harmful substances that can then be eliminated from the body. While coffee is indeed a stimulant that can increase alertness, it does not speed up the metabolism of alcohol or mitigate its effects. Therefore, drinking coffee after consuming alcohol may make a person feel more awake or alert but does not reduce blood alcohol concentration or accelerate the elimination process. This is a common misconception; caffeine may mask some of the sedative effects of alcohol but cannot negate the alcohol itself, potentially leading to dangerous situations where a person may feel fine but still be impaired. Understanding this concept is crucial for safe driving and responsible alcohol consumption.
