Final answer:
The Cherokee would get the largest piece of land. According to the Dawes Severalty Act of 1887, each head of a Native American family would receive 160 acres of farmland or 320 acres of grazing land. Option A.
Step-by-step explanation:
The group of Native Americans who would get the largest piece of land under the Dawes Severalty Act of 1887 would be the Cherokee.
The Act allowed the federal government to divide tribal lands and grant 160 acres of farmland or 320 acres of grazing land to each head of family.
It is important to note that the Act assigned Native Americans the most arid and useless land, while the 'surplus' land went to White settlers.
Hence, the right answer is option A.
