Excerpt from the fall of the house of usher
edgar allan poe

the room in which i found myself was very large and lofty. the windows were long, narrow, and pointed, and at so vast a distance from the black oaken floor as to be altogether inaccessible from draperies hung upon the walls. the general furniture was profuse, comfortless, antique, and tattered. many books and musical instruments lay scattered about, but failed to give any vitality to the scene. i felt that i breathed an atmosphere of sorrow. an air of stern, deep, and irredeemable gloom hung over and pervaded all.

which idea from the passage is really an opinion?
a) dark draperies hung upon the wall.
b) there are large fissures upon the walls.
c) the windows were long, narrow, and pointed.
d) musical instruments usually give a sense of vitality to a room.
