i would making noises(A), why?
Cuz' we do not understand their language, but they actually do talk.
Our ears are just closed from understanding there language.
Also, look at the fish, only after people have created a microphone thing, then only at that point we know now, that fish make noises, and our ears were closed!!! only after the scientists made the thing, then only we now know that there are noises in the water.
Hope that this would help you! =)
