Answer:
A - Increasing transportation
Explanation:
The area that was improved in North Carolina during the 1830s, after years of lagging behind the rest of the nation, is "increasing transportation."
Before 1830, North Carolina lacked any development, and the economy was based on cotton farming and slavery.
However, after a series of name-calling by other states, calling North Carolina the "Rip Van Winkle" for "sleeping" while other states in the Nation progress, many of the people in North Carolina decided there must be a positive change.
Between 1830 to 1861, when the American civil war began, North Carolina built roads, railroads, and ships to transport farm produce and humans.
This period is known as an antebellum period.
Hence, in this case, it is concluded that the correct answer is option A. "increasing transportation."
