Solution

The correct option is B Eustachian canal
The middle ear contains three small bones collectively called ossicles, which involved in the transmission of sound and is connected to the throat via the eustachian tube. It controls the pressure within the middle ear, making it equal with the air pressure outside the body.
So, the correct answer is 'Eustachian canal'.
