Answer: what school do you go to?
Explanation:
Since the 'inciting incident' is the one which starts all the problems in a literary work, the answer is B, 'establishment of the central conflict followed by the conflict increasing and a climax'.
There are many themes in romanticism but in my personal opinion the prominent theme would be that of emotion in its naturalist state. I can not guarantee you that each and every scholar agrees on this but inspiration and connecting emotionally with nature is what Romanticism heavily relied on.
Hope this helps! If you have any other questions or would like further explanation just let me know! :)
