Answer:
A. haunted and wild
Step-by-step explanation:
In "Kubla Khan", Coleridge starts with the description of Khan's pleasure dome, Xanadu, laying on the sacred river Alph.
Although we might expect a more detailed depiction of this palace and its purpose, the author quickly shifts to the stream of river which quickly becomes wild downstream of the palace.
This is because of the chasm in which the river flows, that is described as:
"A savage place! as holy and enchanted
As e'er beneath a waning moon was haunted
By woman wailing for her demon-lover!"
Such description of the nature (savage, wild and haunted) is in contrast with the descriptions of the romantics, to which Coleridge belonged, which opens many ways to interpret this poem.
