I believe that the answer is B. A savage place! As holy and enchanted / As e’er beneath a waning moon was haunted / By woman wailing for her demon lover!” because it talks about a supernatural being, a demon, being someone's lover.
There is a description of a savage place that is enchanted.This is something unreal and supernatural.Apart from that there is another element, the haunted moon.Haunting is another supernatural detail depicted in romantoc poetry.A demon lover gives an image of a monstruous being which is also part of this fascination about all that was obscure and from another world or reality.
