The right answer is the D) Whitman’s poem has a very similar title.

Explanation: Just to elaborate a little on the answer, it can be added that in these two opening lines from his powerful poem, I, Too, Langston Hughes (1902-1967) is clearly referencing Walt Whitman's celebratory poem I Hear America Singing, in which he describes the various sounds he hears coming from American people performing their daily activities—that of the mechanic, the carpenter, the shoemaker, the mother, and so on. Instead of "hearing America singing," Langston is "singing America," in order to raise his voice against the discrimination that African Americans had to endure for centuries in their own country.
