Explanation

The braking distance can be influenced by the weight of the motor vehicle, the wear of the tyres, the travelling speed, the grip of the tyres on the road and the reaction time of the driver. However, the braking distance depends the most on the speed at which the motor vehicle travels.

The correct answers are A and B.
