The native american protested against the ill practices done by the government policies.
<u>Explanation:</u>
The native Indian Americans were not treated nicely by the government and the policies formed by the government were mostly not in favor of the native Americans. These native Americans formed leaders of their group and they together as a group protested against the high rate of unemployment or against the taking away of the land of these groups.
The leaders of this group also protested against the discrimination which was done against them. They wanted right to be treated properly and reclamation of their land back to them.
The correct answer is "Accusations of bribery against the Grant Administration."
This can be the only correct answer, as the first, second, and fourth statements are incorrect.
Even though Grant (a Republican) won the election of 1868, he actually helped with Reconstruction. Grant sent in federal troops to help protect the rights of African-Americans in the Southern states. This shows that the first two statements are incorrect.
The fourth statement cannot be correct, as it was the Democratic party who lead attacks against the voting rights of African-Americans during Reconstruction.
This shows that only the second one can be correct.
