The correct answer to the question "Who lived in America before the Europeans arrived?" is American Indians.

Explanation:

Before European explorers and settlers arrived in the Americas, the continent was inhabited by a diverse range of indigenous peoples, collectively referred to as American Indians or Native Americans. They had established complex societies, cultures, and economies long before the arrival of Europeans in the late 15th century. Each tribe had its own language, customs, and historical traditions, and these groups were spread across the continent, from the Arctic regions to the southern tip of South America.

The other options presented—immigrants, pioneers, and "no one"—do not accurately reflect the history of the continent before European contact. Immigrants and pioneers typically refer to European settlers who arrived after the initial contact, while stating "no one" negates the rich history and presence of indigenous peoples who had been living in the Americas for thousands of years.
