So the correct answer is option E) breakup tribal landholdings.
From the 1880s to the New Deal, the dominant United States government policy toward American Indians was to break up tribal landholdings.
One of the best examples was the Indian Removal Act. Andrew Jackson encouraged westward expansion and settlement by supporting the Indian Removal Act.
On May 28, 1830, United States President Andrew Jackson signed the famous Indian Removal Act that supported the westward expansion and invited many Americans to settle territories in the west. These were territories west of the Mississippi, and the President could grant lands in exchange for Native American Indian tribes' lands that already existed within the known US territory.
So this act gave powers to the US President to negotiate the removal of the Native Indians to other territories. The President wanted to support white settling to farm the lands and make them productive.
