Answer : A. Engage your anti lock braking system
Explanation:
If you encounter a situation where you are not able to avoid the hazard then you should engage your anti-lock braking system because anti-lock braking system helps you steer safely by restoring traction to your tires. It helps prevent wheels locking up allowing driver to steer safely.
If you accelerate immediately or set the wheel to cruise control then probability of accident increases. In an attempt to steer around, chances of accident are also more.
