hi guys, I need help again! This question is kinda tricky though.. I have to say..:
Consider what would happen if the optic nerve from your eye and the auditory nerve from your ear were switched. if during a thunderstorm you saw lightning,  you
A. would hear strange noises and see repetitive lightning flashes
B. may see multiple lightning flashes but would hear no thunder
C. may hear strange noises but would not see any lightning
D. would neither hear nor see anything

This one.. i seriously have no clue.. but i need an explanation for the answer please.
