Why Did the Rise of the Market Revolution and Westward

Why did the rise of the market revolution and westward expansion make life worse for African-Americans?

A) The rise of the Cotton Kingdom reduced legal slavery dramatically, and slave trading became an underground business in which traders forced enslaved people to march to the Deep South.
B) When traders and owners moved enslaved people west, they destroyed family ties and long-standing communities.
C) The decline in slavery meant that free blacks were forced to find their own source of income, which they had no experience doing.
D) Federal law barred free blacks from skilled job opportunities.
E) Travel fees grew too expensive for black families to afford finding economic opportunity in the West.
