Which tribe had the largest land holding in acres, totaling 16 million acres across Utah, Arizona, and New Mexico?

• A. Hopi Reservation in Arizona
• B. Cherokee Nation in Oklahoma
• C. Navajo in Utah, Arizona, and New Mexico with 16 million acres
• D. Sioux Nation in North Dakota

Answer: (C)

Understanding land area held by a Tribe is about how large the reservation is and where it sits. The Navajo Nation is the one that fits both parts here: it covers portions of Utah, Arizona, and New Mexico and totals about 16 million acres. That scale—millions of acres across three states—makes it the largest land holding listed. The Hopi Reservation is entirely within Arizona and much smaller; the Cherokee Nation is centered in Oklahoma (not spanning those three states) and is smaller in total area; the Sioux Nation listed is associated with North Dakota and nearby areas, not a 16-million-acre multi-state footprint. So the Navajo Nation is the correct example of the largest land holding among those options.
