Answer:
b. To help former slaves to get food, shelter, clothing and education.
Explanation:
The southern reconstruction is a period when the former-slaves that freed during the civil war tried to transitioned to citizenship.
At that time, many southern people still openly treat the former-slave horribly. They attack them when they're out at nights, not hiring them for any types of jobs, etc.
This made it really difficult for the formers slaves to survive. The Freedmen's bureau was established to help them. As one of their programs, the Bureau help former slaves to get food, shelter, clothing and education.
