Correct answer: B. The road holding ability of the vehicle is reduced.
Driving at high speed is a factor that affects road holding. At higher speeds the airflow under a vehicle reduces tyre grip on the road and when you are approaching a bend or corner, the momentum of the vehicle makes it more difficult to change direction.
