On ice or snow, it is advisable to drive...

A)using the lowest possible gear ratio.
B)braking hard on bends.
C)using the highest possible gear ratio.Correct
When driving on ice or snow, there is a risk of the vehicle skidding. If a low gear ratio is used, it will generate too much power and the wheels will simply spin on the ice or snow. On the other hand, if a high gear ratio is used, the wheels will not spin as much due to the lower power output.
To move off on snow, use second or third gear to prevent the wheels from spinning. While driving, try to use the highest gear possible, driving very smoothly. Remember that in such situations the braking distance increases considerably, so you must drive with caution and adjust your following distance accordingly.
