Answer: A. From the American soil and air.
In "Song of Myself," Walt Whitman displays his poetic vision and reflects on his "self" (which is the speaker, though not necessarily Whitman). The poem is written in free verse style and uses simple, common words in order to appeal to a larger audience. The poem displays elements of various literary movements, such as Romanticism, Transcendentalism and Realism. It represents both a celebration of America and a reflection on its gritty details of everyday life (such as slavery).
