What should you do if you encounter black ice on the road?

Accelerate to gain traction.
Brake suddenly to slow down.
Steer in the opposite direction of the skid.
Reduce your speed and drive with caution.

The correct answer is: Reduce your speed and drive with caution.

You should reduce your speed and drive with caution if you encounter black ice on the road. Black ice is a thin, transparent layer of ice that forms on the road surface, making it extremely slippery and difficult to see. Accelerating may cause your car to lose control and brake suddenly can cause you to skid further. Steering in the opposite direction of the skid is also not recommended as it can cause your vehicle to spin out of control. Therefore, reducing your speed and driving with caution is the best way to safely navigate through black ice on the road.
