The answer is: C. dry, twilit limbo.
In the poem "The Hollow Men,! by T. S. Eliot, the men gather on the banks of a "tumid" river:
"In this last of meeting places
We grope together
And avoid speech
Gathered on this beach of the tumid river"
The men are close to one another without saying a word - they are unable to seek God's redemption. As a result, their souls are stranded betweel hell and heaven.
