Answer:
I believe the answer is D: African Americans in large urban centers created the blues to tell stories about the'r lives.
Explanation:
I'm not TOTALLY 100% sure though, it's just an educated guess. See, I live in Louisiana, and I've heard something about how the freed African American slaves used blues to tell stories about their lives. Although this could be a completely unrelated. Either way, I hope it helps and you get a good grade. :)
