Final answer:
Without the specific context of a story, it is challenging to accurately determine why Emily would have a dead body in her house. The closest literary example is William Faulkner's 'A Rose for Emily', where the discovery of a dead body reveals key psychological and thematic layers within the plot.
Step-by-step explanation:
The question regarding why Emily would have a dead body in her house references a narrative, likely from a piece of literature, where the potential reasons for having a dead body present cover a range of scenarios. However, none of the given choices precisely match known excerpts or common scenarios in literature without the specific context of a story. To provide an accurate answer, it is necessary to know the specific narrative in question. If we refer to William Faulkner's A Rose for Emily, we might infer that the dead body is someone significant to her, as presented in choice c) The dead body was her father's. Such details become significant as they unravel the psychological and thematic layers present within the plot. In literature, the presence of a dead body might serve various thematic purposes, such as exploring themes of death, decay, and the individual's struggle against societal constraints or personal loss.
