Final answer:
The correct answer is option D. Reduce.The correct answer to when making a turn is to reduce your speed, which is essential for safety and control.
Step-by-step explanation:
When making a turn, it is important to reduce your speed for safety reasons and to have better control over the vehicle during the turn. Acceleration can occur in three different ways according to physics: by speeding up, slowing down, or changing direction. Reducing speed is a form of deceleration, another term for negative acceleration, and is essential when turning to avoid losing control of the vehicle and to navigate the turn safely.
This is important because turning requires changing direction, and reducing your speed helps ensure that you can safely negotiate the turn. When you turn, your vehicle is subject to lateral forces that can cause it to lose traction if you are going too fast. By reducing your speed, you increase your vehicle's stability and control, minimizing the risk of accidents.
