Tina was born with hearing impairment.When Dr.Albert studied the physiology of her auditory system, he found that Tina's eardrums were intact and were receiving auditory stimulus.However, the stimulus was not moving forward from the eardrums and was not reaching the inner ear.Which of the following conclusions is Dr.Albert most likely to have drawn from these findings?

The hammer, anvil, and stirrup in the middle ear are responsible for transmitting auditory stimuli from the eardrum to the inner ear. Since the eardrums are intact and receiving auditory stimuli, the issue must lie with these tiny bones in the middle ear not performing their functions properly. The other options, such as damage to the cerebral cortex or occipital lobe, would not affect the transmission of auditory stimuli from the middle ear. The pinna in the outer ear helps to collect sound waves, but it does not play a role in transmitting auditory stimuli to the inner ear.
