The correct answer is - C. the effects of Reconstruction on former slaves in the South.
During the Reconstruction, the slaves in the South managed to gain some rights, and they were able to produce for themselves, instead of working for someone else.
The sharecropping, essentially, meant that a large and rich landowner would land finances and land for the people, including the former slaves, and they were able to work and produce for themselves, but also had to pay certain percentage to the person that was landing the finances and land.
This process improved the living conditions and the financial status of lots of families in the South, especially the ones of the former slaves.
