Solution

The correct option is B Pressure inside the balloon is greater than the atmospheric pressure
The air inside the balloon exerts pressure on the walls in all directions. Once the mouth of the balloon is left open, the entire air escapes to the atmosphere. This is because the pressure inside the balloon is greater than the atmospheric pressure.
