Answer options with 4 options
A.
The air and the balloon have opposite charges, so they repel each other.
B.
The air and the balloon exert forces on each other in opposite directions.
C.
The air has a lower density than the balloon, so the balloon sinks and the air rises.
D.
The balloon pushes with more force than the air, so the balloon moves away from the air.

The correct answer is:
B. The air and the balloon exert forces on each other in opposite directions.
This is a demonstration of Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. When the air rushes out of the balloon, it exerts a force downward, and in response, the balloon is propelled upward.
