Name one American Indian tribe in the United States.

The correct answer is Cherokee, which is one of the prominent American Indian tribes in the United States. The Cherokee Nation is historically known for its rich culture and significant political and social structures. They played a crucial role in early American history, particularly during the expansion of European settlers into their territory. The impact of the Trail of Tears is especially notable, as it was a significant and tragic event in the history of the Cherokee people, reflecting the struggles faced by Indigenous tribes due to displacement and forced removal policies.

The other options refer to groups that are not native to the United States. The Igbo are an ethnic group from Nigeria, the Maori are the indigenous people of New Zealand, and the Sami are indigenous to parts of Norway, Sweden, Finland, and Russia. Each of these groups has unique histories and cultures, but they are not recognized as American Indian tribes within the United States. Thus, Cherokee stands out as the correct choice in this context.
