To accurately determine the best description of the mood in the selected passage from "A Christmas Carol," I would need to analyze the specific text in question. However, considering the common themes and typical scenes involving Scrooge and the ghosts in the story, the mood often leans towards fear and unease due to the haunting nature of the ghostly visits.
If the passage depicts Scrooge's confrontation with a spirit that reveals truths about his life and potential changes in his fate, it is likely that the most fitting mood would be "Fear and unease, as Scrooge is confronted with something terrifying and struggles to maintain control."
