Read the second stanza of the poem "The Raven" by Edgar Allan Poe. Ah, distinctly I remember it was in the bleak December,
And each separate dying ember wrought its ghost upon the floor.
Eagerly I wished the morrow; —vainly I had sought to borrow
From my books surcease of sorrow—sorrow for the lost Lenore—
For the rare and radiant maiden whom the angels name Lenore—
Nameless here forevermore.

Which line from the stanza best supports the idea that the speaker wasn't expecting anyone to come by?
A: "'Tis some visitor," I muttered, "tapping at my chamber door—"

B: "Over many a quaint and curious volume of forgotten lore—"

C: "As of someone gently rapping, rapping at my chamber door"

D: "While I nodded, nearly napping, suddenly there came a tapping,"
