Final answer:
The Anasazi formed a large community and built a remarkable series of cliff dwellings in Chaco Canyon.
Step-by-step explanation:
The correct answer is A) Chaco Canyon.
The Anasazi, also known as the Ancient Puebloans, built homes in cliff dwellings that still exist today. Chaco Canyon in New Mexico is one of the most remarkable locations where the Anasazi formed a large community and built a series of cliff dwellings, including the famous Pueblo Bonito site.
These cliff dwellings were carefully planned communities and provided ample living space and storage room for the Anasazi people. They were built high on canyon walls or atop mesas, providing protection from nomadic raiding groups.
