Final answer:
In foggy conditions, using high beam headlights blinds other drivers due to the reflection and scattering of light by the water droplets in the fog, reducing visibility.
Step-by-step explanation:
When driving in foggy conditions, you should not put your headlights on high beam because it blinds other drivers. Using high beams in fog can cause light to be reflected by the water droplets, scattering it and actually reducing visibility rather than improving it. This can make it more difficult for you to see the road, and also has the potential to blind other drivers, which can increase the risk of accidents. Moreover, high beams can create a white wall effect, making it almost impossible to see anything in front of you. The correct answer to the question is B) It blinds other drivers.
