What elements of the description of the caverns contribute to the mood of approaching danger?

(a)-the caverns where fortunato keeps his wine cellar are an old crypt, it is not spacious, it is dark, and the walls are lined with human remains piled high to the vault overhead.

(b)-the cavernous catacombs are organized with narrow recesses of 3x4x6 or 7 feet surrounded by walls of solid granite, suggesting montresor is about to murder fortunato in one of these recesses

(c)the two men require torches to see in the dark caverns: fortunato’s torch is described as "dull" with a "feeble light that did not enable us to see."

(d)-all of the above contribute to the mood of approaching danger as fortunato proceeds down the corridors of his wine cellar with montresor.
