Answer: C-focused on mining and agriculture
Step-by-step explanation:
As the early Americans adhered to the Manifest Destiny and expanded to the Western part of the Continent, they engaged in different activities from their Northwestern counterparts.
The territories that the Americans took over to the west had fertile land for agriculture as well as rich mineral deposits which led to minning. This often put them at loggerheads with the Native Americans and differentiated them from the North Eastern states which were more industrialized.
