Extreme weather conditions significantly impact both traction and visibility, making option B the most appropriate choice.

In situations such as rain, snow, fog, or ice, the road surface becomes slick, which can drastically reduce traction, resulting in longer stopping distances and loss of grip when cornering. Drivers must adjust their driving techniques to maintain stability and avoid skidding.

Visibility is also severely affected by adverse weather conditions. Heavy rain, fog, or snow can obscure a driver's ability to see road signs, other vehicles, and obstacles, increasing the risk of accidents. Reducing speed and ensuring proper use of headlights becomes critical under such circumstances to enhance visibility for both the driver and other road users.

The other factors listed do play a role in driving, but their influence is not as immediate or significantly impaired by extreme weather conditions as traction and visibility.
