The correct answer is A. The Homestead Act greatly impacted the American Indians of the Great Plains by encouraging homesteaders to take over the American Indians' farms.

Explanation:

The Homestead Act was a law of the United States of America created by President Abraham Lincoln on May 20, 1862.

Large contingents of European immigrants participated in the occupation of the vast west of the United States, and without them this achievement would not take place. To attract immigrants, the US government decreed in 1862 the Homestead Act, which defined the ownership of a property of 65 hectares to those who cultivated it for five years. Anyone who had never taken up arms against the US government, including freed slaves, could file a claim for a federal land grant. This law greatly increased the flow of European immigrants to the United States, but many of the lots they acquired were taken from Native Indian tribes.
