The Eustachian tube is used to equalize air pressure between the middle ear and the surrounding area(tympanum) Keeping the pressure in a person's head equalized helps with balance and preventing dizziness.
Yes opt A is correct
cos, the tube allow Air from the surrounding to enter or leave the middle ear so that the air pressure on both sides of the eardrum is equal
The answer can't be B because even just using sense to answer you see that the tube leads downwards towards the mouth side and not upwards towards the brain so it can't send waves to the brain at all. That's s why sometimes when you put eardrop in your ears you can taste it in your mouth. it passed through that tube
