Answer: B — Seek medical advice before driving

If you are taking medication, it is important to seek medical advice before driving. This is because some medications can cause drowsiness or affect your reaction time, making it unsafe to drive. The other options are incorrect because they do not address the potential effects of medication. Driving only short distances or taking a shorter route do not guarantee safety while driving on medication, and limiting driving to daytime does not take into account the possible side effects of different medications that may affect driving ability at any time of day. Seeking medical advice before driving is the best option as it allows for a professional evaluation of the potential risks and appropriate precautions to take while on medication.
