The experiment involved causing the axons of retinal ganglion cells in the visual system to synapse in the auditory system. Therefore, when the ferrets matured, the auditory cortex responded to visual stimuli, indicating that the neural connections between the visual and auditory systems had been established. Additionally, since the retinal ganglion cells are organized in a specific spatial pattern (known as retinotopic organization), the auditory cortex would likely be laid out retinotopically as well. Thus, both options A and B are correct. Option C is not correct as there is no indication that the auditory cortex degenerated as a result of the experiment.
