Why is it important to apply both brakes together on wet surfaces?

Answer: B — To prevent skidding

Applying both brakes together on wet surfaces is crucial to prevent skidding. When the road is wet, traction between the tires and the surface is reduced, making it easier for the rear wheel to lose grip if only the front or rear brake is used. By using both brakes simultaneously, the rider distributes the braking force more evenly and maintains better control over the motorcycle, which minimizes the risk of the tires slipping. This coordinated use of both brakes aids in stopping more effectively while reducing the chance of losing traction, thereby enhancing overall safety in wet conditions.
