From the speech I have a dream.

This speech is an example of which kind of writing? A) descriptive B) expository C) narrative D) persuasive

The answer is C) Narrative. A narrative is a form of storytelling that involves characters and plot structure (a beginning-middle-end structure)

So, like, a narrative would be like if I sat down with you and told you about my day. A non-narrative story would be if I made a timeline for you, with events of my day placed in chronological order. They can "tell" the same thing, but a narrative is often a more engaging, emotional story experience.
