Answer:
D. Inertia
Explanation:
This is an example of centripetal (circular) motion. The water stays in the bucket because of inertia. The water wants to fly off from the circle, but the bucket gets in the way and keeps it in place. This is the same effect you feel when you go around a tight corner in the car and get squished against the door.
