Solution

The correct option is B Eustachian tube
Eustachian tube is a hollow structure that extends from the middle ear to the pharynx (throat). The main function of the eustachian tube is ventilation of the middle ear and maintenance of equalized air pressure on both sides of the eardrum allowing it to vibrate freely.
