Read the following sentence from the article. This country's music is an advertisement for 400 years of the opposite: centuries of "amalgamation" and "miscegenation" as they long ago called it, of all manner of interracial collaboration conducted with dismaying ranges of consent. Which sentence from the article BEST supports this idea? (A) Particular to black American music is the architecture to create a means by which singers and musicians can be completely free, free in the only way that would have been possible on a plantation: through art, through music — music no one "composed" (because enslaved people were denied literacy), music born of feeling, of play, of exhaustion, of hope. (B) There was, perhaps, not a white audience in America, particularly in the South, that would not have resented, in a very energetic fashion, the insult of being asked to look at the majestic singing of a real Negro. (C) After the Civil War, black performers had taken up minstrelsy, too, corking themselves, for both white and black audiences — with a straight face or a wink, depending on who was looking. (D) The proliferation of black music across the planet — the proliferation, in so many senses, of being black — constitutes a magnificent joke on American racism.
