Answer:
I believe the answer is A, Plain or implied.
Explanation:
I used process of elimination and examined how the other answers would look with the blanks. Saying the meaning of a story is "real or fiction", "strong or weak", or "right or wrong" would seem incorrect considering that stories typically have the intent of indirectly teaching the reader a good quality, and if we're focusing strictly on how that message is presented, it would be most logical to say that A is correct, though I apologize if I'm wrong.
