Which statement best describes the external auditory canal?

Explanation:
The external auditory canal’s main function is to act as a conduit for sound entering the ear. It’s a tube that carries sound waves from the outer ear to the eardrum, and its shape helps to slightly amplify certain frequencies, which aids hearing. It also provides protection with earwax and hair. It does not carry visual information or regulate ear temperature, so the best description is that it serves as a pathway for sound into the ear.
