Explanation

Before the American civil war in the nineteenth century, the situation of the country was problematic due to the deep division that there was between the states of the north and the states of the south. While in the northern part the economy was based mainly on industry and there was no slave regime, in the south the economy was centered solely on agriculture and in which there was a definite pattern of slavery. This situation added to the growing territorial expansion of the country and constant uncertainty about the future caused the northern and southern society sectionalism. So, the correct answer is B.
