The meaning of the question is basically pick a story, pick one event(preferably major) from this story, and explain how it contributes to the moral of the story
The correct answer should be B) Listing all the arguments that could be made about the topic that interests you most because the key word is ''pre'' so that means before, so before you start writing the stage, that's what I would do so I can first find a topic, then research it, then, highlight some main ideas for supporting evidence, next I would ask someone to check it and lastly send it in.
I personally would go with D it just sounds better than all the other choices but I'm not 100% sure
