D. jesse's car is a hybrid that shuts off extra pistons when it is not accelerating
<h3><u>Explanation;</u></h3>
- When cruising, hybrid cars are able to employ electrical energy to drive the car.
- Moreover, even if a vehicle is not a hybrid, a greater amount of fuel is consumed when one accelerates because the vehicle has to generate a force larger than the force of air resistance in order for it to accelerate.
- This increased demand of force reduces the vehicle's fuel economy.
