Based on the information provided about the Indian Removal Act of 1830, the correct answer would be:
- Give Native American nations money and new land in exchange for their land in the East.
The Indian Removal Act authorized the president to set aside land for Native American nations west of the Mississippi River, pay them for their land in the East, and assist with their relocation to the new land, which aligns with this option. The other options do not accurately reflect the provisions of the Indian Removal Act.
