The correct answer is "to teach a moral by delighting the reader with a good story."
The purpose of fables is to teach a moral by delighting the reader with a good story.
A fable is an interesting or funny story but its main characteristic is that at the end of the story there is a lesson in morals. Something that the reader can learn that is meaningful for its life. The fable is a way to teach us something of value through a story that can entertain us and that could be understood in an easy way.
Among the most famous fables, we wave "The Lion and the Mouse.," "The Turtle and the Hare," or "The Fox and the Crow."
