Solution

The correct option is D The atmospheric pressure decreases with height
The atmospheric pressure exists due to weight of atmospheric gases above a certain given height. As one goes high, the weight of atmosphere above decreases and so does the pressure. Thus for a balloon filled on ground, the pressure inside the balloon exceeds that outside and thus it bursts.
