Answer: B
Step-by-step explanation:
The tone of "Harlem" by Langston Hughes is bitter. The poem explores the theme of deferred dreams and unfulfilled promises, and it expresses the frustration and disappointment of the African American community. The speaker in the poem wonders what will happen to a dream that is "deferred," or put off or delayed, and whether it will "dry up like a raisin in the sun." The use of the word "bitter" in the last line of the poem, "Or does it explode?" suggests a sense of anger and resentment towards the societal conditions that prevent people from realizing their dreams.
