D)The walls of the rooms were discordantly papered
Explanation:
cause all the other ones explain what's going on not where the person in the story is and you can imagine where the person in the story is

Not sure if you're given actual answer options but from what I can see, I can conclude that the answer should be auditory :) hope this helps!
