A ballon’s floats inside a stopped car when the car starts moving forward the ballon appears to move backwards relative to the car which statement best explains this observation

The best explanation for this observation is that of relative motion. When the car starts moving forward, the balloon is initially stationary relative to the car. However, as the car accelerates, the air inside the car moves towards the back of the car due to inertia. This causes the balloon to appear as if it is moving backwards relative to the car, even though it is actually still moving forward along with the car.
