Solution
The correct option is A Blocked eustachian tube A. Blocked eustachian tube
EXPLANATION: The eustachian tube connects the middle of the ear to the nose and throat. This tube helps to regulate the ear pressure. Ear barotrauma is caused by air pressure changes at higher elevations. This results in discomfort and pain in the ear also. It happens due to the blockage of eustachian tube at higher elevations.
