Answer: D, specifically the bit about "the fall of man."
Explanation: An allegory is a story told in familiar language, intended to shed light on matters in some unfamiliar area, such as spirituality, honor, or custom. Similar terms include parable and fable. An allegory usually has many details of the familiar story which make sense when the story is read simply, but which also match up with details of the unfamiliar topic. This is different from a parable, which usually has a single primary point, matching up with a point in the unfamiliar area; other details generally flesh out the simple story and generally don't match to details of the unfamiliar story. Similarly, a fable usually focuses on moral considerations, often telling the familiar story using animals instead of people; again, there is basically a single point of corresponence, the "moral of the story."
