In the 1700s, free african americans mostly lived in rural areas. on plantations. in small towns. in large cities.

In the 1700s, slavery was still a concern for African Americans. Free African Americans preferred to live in the Northern cities, where there was less slavery, and so they wouldn't be seen so differently. Of course, equality is still a problem today, but it was less of a problem in Northern Cities when compared to the Southern cities, historically more prone to slavery.

The correct answer would be alternative D)"Large Cities", especially the ones in the North.
