B. Replace

Explanation:

One purpose of the Black codes was to find workers to replace enslaved people.

After the North (Union) won the Civil War, Southern states sought to still keep Black Americans at a lesser status than Whites and because they had just lost their labor force - enslaved people - they wanted a way to get them back.

Black Codes were so restrictive on Black people that one could easily see that they were passed simply to get Black Americans back on the plantations doing hard labor because some of the penalties involved arresting Africa Americans and making them work for free.

it affected it because the kingdoms (with trade) slowly got richer and richer.

regarding the law, the 15th amendment was specifically designed thinking in the rights of black free men.

even though ratified on february 3, 1870, the promise of the 15th amendment would not be fully applied for a long time.poll taxes and literacy tests would allow southern states disenfranchise african americans. only in 1965 the voting rights for african americans would be actually able to vote in the south.

in 1965, president johnson signed the voting rights act, which aimed to overcome legal barriers that prevented african americans from voting as it was guaranteed by the 15th amendment to the u.s. constitution.
