Why was the Freedmen’s Bureau established? to provide freedmen with healthcare and education
to advocate for freedmen to gain the right to vote
to give land from former slaveholders to freedmen
to assist freedmen in running for public office

Explanation:

After the Civil War and 13th Amendment, slavery was abolished from the United States. This left 4 million former slaves or freedmen to fend for themselves while looking for jobs, homes, and educations during the period of Reconstruction.

The Freedmen's Bureau was created by the government to help the freedmen transition. They helped tons of former slaves through meals, healthcare, labor contracts, and the building/funding of schools and colleges.

They attempted to redistribute land (choice C) but most efforts were unsuccessful and it wasn't the main purpose. It was not created for suffrage (choice B) or to help prospective politicians (choice D). This leaves choice A as the best answer.
