Which of the following would most appropriately state the theme of a story?

a. it's a story about a flea who has it out for a dog.
b. it's a story about how an obsessive desire for revenge can ruin a person.
c. dogs and fleas are both silly.
d. none of the above.

B is the correct answer. A theme is a message or moral rule the author is trying to convey. The theme wouldn't include the actual characters in the story, only what they symbolize. To give an example; in the Turtle and the Hare story, the theme isn't "Slow and steady turtles beat fast and clumsy hares"; the correct theme is "Slow and steady wins the race".

I hope this Helps!
