Which novel describes the economic, political, and settlement of Western Virginia after the American Revolution?

The novel "O Beulah Land," authored by a prominent regional writer, specifically focuses on the post-American Revolution era in Western Virginia, detailing the economic, political, and settlement patterns of that time. It portrays the struggles and developments faced by early settlers as they navigated their new lives in the aftermath of the war and reflects the broader societal changes occurring during the westward expansion.

The other choices do not address this historical context. "Song of the South" is a collection of stories that depict life in the Southern U.S., namely focused on racial themes and folklore. "Gone with the Wind" deals with the American South during the Civil War and Reconstruction, primarily through the lens of Southern society in Georgia. "The Good Earth" centers on rural life in China around the early 20th century, focusing on themes of agricultural life and social issues.

Hence, "O Beulah Land" stands out as the correct option because it directly engages with the specific themes of settlement and socio-economic conditions in Western Virginia following the American Revolution.
