Solution

The correct option is A
Air inside the balloon exerts pressure in all directions.

The air inside an inflated balloon exerts pressure on the balloon. This pressure in balloon is greater than atmospheric pressure. Hence, when the balloon is punctured, air escapes from inside the balloon to the atmosphere.
