Answer: D.found work in northern cities.
Explanation:
During the war, the North faced significant growth in the industrial economy, and the lack of European immigration urged businesses to hire black southerners that had arrived in cities such as Chicago, New York, Cleveland, Pittsburgh, and Detroit, looking for higher wages and improved working conditions. The Great Migration had roughly 500,000 black southerners moving up north between 1914 and 1920.
