Final answer:
The definition of a narrative encompasses character development, plot events, and a structured beginning, middle, and end, but does not necessarily include a humorous situation as an essential element. The correct answer is option d.
Step-by-step explanation:
The definition of a narrative includes several key elements such as character development, plot events, and a structured beginning, middle, and end. However, the inclusion of a humorous situation is not a necessary element of all narratives. While humor can be included in a story, it is not a defining characteristic of the narrative form itself. Narratives focus on the development and change of characters over time, the sequence of events (plot) that occurs, and the overall arc that structures the story from start to completion.
