The ossicles (the three tiny bones in the middle ear) are responsible for a. converting sound vibrations into neural signals b. relaying sound vibrations to the eardrum c. vibrating in response to sound waves d. amplifying sound vibrations from the eardrum

The answer on ED:

D. "amplifying sound vibrations from the eardrum"

D.  amplifying sound vibrations from the eardrum

Explanation:

The ossicles are the three tiny bones that lies inside the middle ear. The sound vibrations from exterior of the ear passes into the ossicles. These ossicles send the sound waves into the inner ear and then the sound finally reaches to the fluid-filled labyrinth that is called as cochlea. The main function of the ossicles is to amplify the sound waves. Inside the cochlea the sound stimuli is converted into electrical impulses.
