Final answer:
Amiri Baraka's poem "Why Is We Americans?" does not use the language feature of dystopia; instead, it includes scat singing, non-standard English, and allusions as its language features. The correct answer is option d.
Step-by-step explanation:
The language feature not utilized by Amiri Baraka in his poem "Why Is We Americans?" is dystopia. In the poem, Baraka employs various language features including scat singing (a vocal improvisation with wordless vocables, nonsense syllables or without words at all), non-standard English (dialects that are not the standard form of language used in writing), and allusions (indirect references to a person, event, statement, or theme). However, dystopia, which refers to an imagined state or society where there is great suffering or injustice, is not a language feature but rather a concept often used in literature to describe an oppressive society or a negative view of the future; it is not directly related to the stylistic choices Baraka makes in his poetry.
