Final answer:
In an emergency situation where traction is lost and the vehicle slides with anti-lock brakes, the correct way to stop is to apply steady pressure to the brake pedal.
Step-by-step explanation:
In an emergency situation where traction is lost and the vehicle slides with anti-lock brakes, the correct way to stop is to apply steady pressure to the brake pedal. Anti-lock brakes (ABS) are designed to automatically pump the brakes for you, preventing the wheels from locking up and allowing you to maintain control of the vehicle. By applying steady pressure to the brake pedal, the ABS system can work effectively to stop the vehicle without losing traction. Therefore, the correct option is 1) apply steady pressure to the brake pedal.
