Yeah I think the correct answer is A.
Can you attach the paragraph?
I would say the correct answer is that - <span>They suggest the narrator is not fully responsible for the outcome of his story.
If something is an accident, it usually means that nobody is at fault because it happened. So when the narrator says that it all happened by chance, it means that he had almost nothing to do with the outcome of his story and that it was fate to happen like that.
</span>
Using short sentences makes the author sound rude. using run-on sentences makes the author seem super talkative. I suggest use medium length sentences to set the tone.
