The statement that was true for most African Americans living in the North is: They had more personal freedom than they would have had in the South.
While African Americans in the North did generally experience more personal freedom compared to the oppressive conditions of the South, they still faced significant challenges, including racism and discrimination. The other statements do not accurately reflect the experiences of African Americans in the North during this period. Racism was present, the cost of living could vary, and relationships with recent European immigrants were complicated, often marked by competition for jobs and housing rather than widespread welcome.
