Answer:
b)The North was becoming industrialized, while the South remained agrarian (farm-based).
Explanation:
The northern states of the USA had a strong industrialization and were the main responsible for supplying the country with industrial pipelines, in addition to having a concentration of industries, machines and free workers, since industries did not adopt slave labor. However, a country needs agricultural products to maintain itself and this production was the responsibility of the southern states, which had a strong agrarian nature and supplied the country with this type of production. Farming work required a great deal of cheap labor and for that reason, these states, for the most part, used slave labor.
