The correct option is A. The issues that caused sectionalism to develop were economic.
Sectionalism is a widespread phenomenon. Sectionalism and slavery exacerbated regional distinctions in terms of economics, culture, and other divisions.
How did slavery cause sectionalism?
Slavery, on the other hand, made the regional and economic divisions between the North and South worse. Southerners blamed the backwardness of their own region on Northern aggrandizement because they disapproved of the substantial gains made by Northern industrialists from marketing the cotton crop.
The result was divisions within the US. Cotton and slavery were the two mainstays of the South's economy. In the West, settlers sought affordable land and reliable transportation, whereas the North's wealth was centered on manufacturing and trade.
The debate over state rights to slavery and the treatment of slaves on an individual basis led to sectionalism. The unusual institution's growth into western territories led to sectional conflict. Since slavery played such a small part in their daily lives, the majority of northerners first chose to overlook the matter.
