The correct answer is A. As a result of the Indian Removal Act of 1830, the Cherokee people had to move west of the Mississippi river.
The Indian Removal Act of 1830 was a law passed by the 21st Congress of the United States to facilitate the transfer of Amerindian tribes living east of the Mississippi River in the United States to lands on the west of the river. The Indian Removal Act, which was part of the US policy known as Indian Removal, was ratified by President Andrew Jackson on May 28, 1830.
