Who lived in America before the Europeans arrived?

The correct answer, A. Native Americans, reflects the historical fact that Indigenous peoples inhabited the land now known as the United States long before the arrival of European settlers. These Native American groups developed diverse cultures, languages, and societies adapted to their various environments across the continent. Their rich history includes complex systems of governance, trade, and spirituality, many of which continue to influence American culture today.

The other options refer to groups that came to America after European exploration and colonization began. European settlers arrived in the 15th century, while Africans were brought to the continent primarily through the transatlantic slave trade that started in the 16th century. Asian immigrants began to arrive in significant numbers in the 19th and 20th centuries. Thus, while all these groups are integral to the history of America, it is the Native Americans who were the original inhabitants of the land prior to European interaction.
