Answer: Fiction, short story, few characters, lesson/moral at the end
Explanation: These are the characteristics of a basic fable. A fictitious story takes place in any setting, usually with a hero and villain. The ending of the story is usually meant to convey a moral lesson about life.
Example: The tortoise and the hare, few characters, no heavy plot/backstory, lesson of "slow and steady wins the race"
The Boy who cried wolf, 1-3 characters, simple plot, moral lesson of "Don't lie because you'll lose trust"
Hope this helps.
