Answer: C — Can affect your driving

Alcohol can impair your driving abilities, even at low levels. When consumed, alcohol affects your brain's function, which can lead to decreased coordination, slowed reaction times, poorer judgment, and impaired vision. This means that even a small amount of alcohol increases the risk of accidents and dangerous situations on the road. While some might believe that low levels of alcohol do not matter or that they feel more alert, this is a misconception, as alcohol negatively influences cognitive and motor skills regardless of the amount consumed. In contrast to the assertion that only high levels affect driving, it is crucial to recognize that any presence of alcohol poses a risk. Always being aware of this can help ensure safer driving and adherence to legal limits.
