Answer:
The correct answer is option C. Multiculturalism.
Step-by-step explanation:
American black literature, virtually ignored before the civil rights movement led by Martin Luther King, Jr. half a century ago, has today become part of America's cultural identity.
As the 1960s began, Americans were becoming consistently permissive and expressive in their sexual and emotional lives, more open and experimental in their responses to literature and art, more playful and outlandish in the styles and ways in which they lived their lives everyday.
