1. Yes, I agree with you that the correct answer is A. Similar to the process used for poetry and fiction. Generally, creative nonfiction has this artistic quality and the basic artistic tenets. It is the prewriting process that is very different, and it includes extensive preparation of facts because creative nonfiction is factual - it doesn't talk about imagined people and events.
2. I would say the correct answer is C. Both a and b. Generally, most fiction, as well as creative nonfiction, has lots of specific details. Both of them have plots - certain chains of events. Also, both have characters. Of course, details are also needed if the text is to be believable or interesting.
3. I also believe the correct answer is D. All the above. A writer should set himself/herself straight before starting to write. They must be acquainted with their own literary taste, capabilities, strengths and weaknesses, affinities and dislikes. Even though writing is by all means a very strenuous job, the writer has to be able to enjoy it if he means to commit fully.
