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.
I’m sorry, I don’t quite understand your question. Would you like to further elaborate so I can help? Let me know :)
