If a public bus starts to experience a rear-wheel skid on a wet road, what is the correct defensive driving response?

1. Slam on the brakes hard and pull the handbrake
2. Steer in the direction of the skid while releasing the accelerator, and avoid sudden braking
3. Steer sharply in the opposite direction of the skid and accelerate
4. Turn off the engine immediately to stop the wheels from spinning
