Ironically, most of free African Americans lived in what region of the United
States?

A lot of free African Americans lived in the North.

Tho A LOT MORE Lived in the South.

(It's ironical but uh here's something on it)

Explanation:

The cruelty towards free blacks was as bad in the north as in the south. Slavery had become a southern affair, but bigotry was truly an issue for all of America. The poor whites nationwide feared free black competition and arranged for numerous race laws in the north and south both. Abraham Lincoln himself believed the racism was too deep seated to be dealt with, and so advocated removing the blacks from the whole country, not just the south.

option b, all states follow similar rules and legal process is the right answer.

the 14th amendment in the constitution of america was enacted in july 1868, which include the citizenship, due process, and the equal protection under the law. this amendment was a response to the issues related to former slaves following the american civil war.

the citizenship clause granted citizenship to all persons born or naturalized in the u.s,.   due process of clause asserted that states may not deny any person "life, liberty or property, without due process of law and the equal protection clause declared that a state may not deny to any person within its jurisdiction the equal protection of the laws. the above mentioned excerpt from the constitution of the united states, ensures the citizenship,due process, and equal protection under the law.
