Solution

The correct option is D the air pressure inside the balloon is high compared to atmospheric pressure.
The air inside the balloon is at high pressure compared to the atmospheric pressure. We know that air travels from high-pressure region to low-pressure region, hence the air comes out of a balloon if it is pricked by a nail.
