C)Double.
The braking distance is that travelled by the vehicle from the moment the driver applies the brake until the vehicle comes to a stop. This distance can vary depending on the speed at which you are driving, the condition of the tyres, suspension, brakes, the vehicle's load, the conditions of the road and the weather.
When driving on icy pavement, the braking distance can be up to 10 times greater. If the pavement is wet, it can be doubled.
