Final answer:
The question pertains to physics and the behavior of balloons when released, which involves Newton's Third Law of Motion. As the air or water is expelled from the balloon, it propels the balloon in the opposite direction due to the action-reaction force pairs.
Step-by-step explanation:
The behavior of the balloon after release involves principles of physics, particularly Newton's Third Law of Motion. When a balloon filled with air or water is let go, the material inside it is under pressure. As this material (air or water) escapes from the balloon, it exerts a force in one direction, in accordance with Newton's Third Law, generating an equal and opposite force that propels the balloon in the opposite direction.
Therefore, the most accurate answer to the question would be:
B. The balloon moves towards the child
This occurs because, as the air or water escapes from the balloon, it pushes backward, propelling the balloon forward in the opposite direction—towards the child. This principle holds for both air-filled and water-filled balloons, with the direction of propulsion dictated by the expulsion of the material from the balloon.
