Question

what should you do before youre about to slow down or stop? check your temperature controls. check your rear view mirror. check your hand position on the wheel.

Explanation:

Before slowing down or stopping, checking the rear - view mirror is crucial for safety. It helps you be aware of the traffic situation behind you, such as the distance of following vehicles, which is important for a safe deceleration or stop. Checking temperature controls has nothing to do with slowing down/stopping, and checking hand position on the wheel is more about driving posture during normal driving rather than a pre - slow - down/stop action.

Answer:

B. Check your rear view mirror.
