It's a run-on cuz there is no and connecting the parts
A . Big bad bill better bring boxes before Bart bails
D developed an outline of your ideas.
I would say b or c. Tbh if it was me answering I would go with c. Hope this helps!!
He's certainly not saying anything that even resembles D. He is talking about something created that was not there before. He is talking about a work produced by the agony of the human spirit to create something that was not there before using the tools available to him. It says nothing about being deserving.
A is a specific group to be addressed. I wouldn't pick it. He says nothing about fellow writers, although they undoubtedly benefit from what he says.
C is too specific. He is not really talking about genius. He would have to classify himself that way, and he doesn't.
That only leaves B. I hate multiple guess because the correct answer is embedded in the mind of whoever asked you the question. I don't like B but of the 4 choices it is the only one you could pick. Be very prepared to be told it is the wrong choice.
