Answer:
B. He borrowed brief phrases from Hughes' poetry.
Step-by-step explanation:
Martin Luther King was a very good friend of Langston Hughes, a poet. Both of them were against the racism that was so prevalent at the time they lived. Hughes was a proponent of Communism which made him a target of the government. King tried to distance himself from him in his speeches by not openly referencing his name when he used quotes from his poems.
King inserted brief phrases of Hughes' poetry in his speech. For example, his quote, "I am personally the victim of deferred dreams..." is a reference to Hughes' poem titled, "Dreams Deferred" which was first named Harlem in 1951.
