c) free whites could marry slaves, but freed african americans could not.
d) free whites could own slaves, but freed african americans could not.

Hey! you do K12 too? anyways you can quickly mark off B and C, as they have no correlation with what the question is asking.

The answer is
A) Freed African Americans had to carry documentation at all times, but free whites did not.

here's why: African americans were seen as "slaves" in those days obviously, so they required to carry 'documentation' or also known as free papers, so they wouldn't be seen as runaways/etc. I don't think i said that right, but white people were not required to carry any because white people were not known to be slaves at that time.

And, if you read frederick douglass's book, (which was more like a diary of being a slave ) he mentions he had to use a paper of some sort to avoid being beaten. Also, if it helps you or makes you feel more comfortable, i have answered this question myself, I hope this answered your question!
