When windows are foggy, you should:

Answer: B — Remove the fog with the defroster

Driving faster may seem like a solution to foggy windows, but it can actually make the problem worse by causing the windows to fog up even more due to the difference in temperature between the inside and outside of the car. Additionally, driving with foggy windows is dangerous and can lead to accidents. Opening the windows is not recommended either, as it can let cold air in and make the car's interior even colder. Wiping the fog off the windows may temporarily improve visibility, but it is not a long-term solution and can be distracting while driving. The best solution for foggy windows is to use the defroster, which uses warm air to remove the moisture and clear the windows. This will ensure safe and clear visibility while driving.
