Verified by Toppr

The eustachian tube is a canal that connects the middle ear to the nasopharynx, It controls the pressure within the middle ear, making it equal to the air pressure outside the body. The pain is caused by unequal pressure that develops between the air in the middle ear and the air outside the ear. Air pressure is highest nearer the ground. So as the balloon rises air pressure decreases. This pushes the eardrum outwards which is painful.
So, the correct answer is option A.
