Which type of writing would most likely include a plot and characters?

The type of writing that would most likely include a plot and characters is a fable. A fable is a short narrative that conveys a moral lesson, often featuring anthropomorphic animals or inanimate objects that embody human traits. These narratives typically involve a sequence of events that develop a conflict or a situation, leading to a resolution that presents the moral.

While a biography and a cookbook may tell stories or provide information, their primary functions do not revolve around a structured plot with characters. A biography recounts a person's life story, focusing on factual details rather than narrative elements like character development or dramatic arcs. A cookbook provides recipes and cooking techniques, lacking a storyline altogether. A dictionary serves as a reference tool, defining words, and does not contain any narrative structure.

Thus, within the context of narrative writing, a fable stands out as it explicitly includes both a plot and characters.
