Unless you are told something about B in your notes, it is outside the realm of the question, although if it is in your notes, it is a possible answer. Looking at the poem as a poem standing by itself, we can say the following.
A: Again if you have notes and this choice is mentioned, it is fair enough. But if there is no mention of it, I don't think it is a choice.
B: We've already discussed B. One thing can be said about Walt Whitman. He certainly wanted a better America, and having been a nurse through the Civil War he wanted a more cooperative America. I don't think that's what your poem here advocates that.
C: This answer feels like a far out answer. I can't see how any part of it would be true.
D: This is not true either. There is nothing about the Oracle judging America. The speaker wants the Oracle to come out of it's cave and give mankind new dreams and new myths to live by.
E: I think E is likely your best answer. Look up, not down.

Self reflexivity is the discipline (in literature) that makes comments internally (in side the work of literature itself) about some part of the work itself. It's sort of like navel gazing and advertising your own virtues.
It's not the first (aqua colored) sentence that reflects this quirk. The first sentence is just a statement.
The second sentence in orange is not right either. It is just a continuation of the first. The only one that is clear cut is the last one (in yellow). That's an example of this trend.
So you have 3 and 4 to deal with. Four expands and explains three. I think I would choose 3, but don't be surprised if it is 4. Notes help.
