You didn't include the choices. But the conflict in fiction provides the basis for the story. It's man against nature, or man finding his place in the world or some such. Without conflict, fiction is nothing but a list of things characters are doing. Nobody wants to read that. No one even wants to write that.
Would you be able to provide the passage it is asking for an answer from?
I'd say A myself, but I'm not 100% sure, hope I helped.
Much of Whitman's prose was guilty by the reason of it being fed by the interconnectedness of nature, and how we, as human beings, relate to this. We also see sensualism and egotism during his "Song of Myself" and "There Was A Child Went Forth". He does inquire in these, that he desires to incorporate all people, and he does talk about the meaning of self.
Also, we see this statement " I loaf and invite my soul, I lean and loaf at my ease observing a spear of summer grass.", Whitman 1049. In his poems, I personally feel though that Whitman was indeed not an egotist, at least for the most part, but mostly and sensualist with egotism implied in certain parts. His sensualistic behavior towards things gives the reader new understanding of a certain perspective.
