Final answer:
When a vehicle moves closer to an object, the safest course of action is typically to decrease speed to allow more reaction time and reduce collision risk. Acceleration can occur by speeding up, slowing down, or changing direction.
Step-by-step explanation:
As your vehicle moves closer to an object, the safest option generally is to decrease speed. This allows you more time to react to unexpected events and reduces the risk of collisions. It is generally not advised to increase or maintain constant speed unless the circumstances clearly warrant such an action. In fact, depending on the object and the situation, you may also have to prepare to stop.

There are three ways an object can accelerate:
- By speeding up,
- By slowing down,
- By changing direction.
Therefore, the correct answer is (b) By speeding up, slowing down, or changing direction.
