Answer:
The correct is c.)Bering Strait
No one knows how or when the first humans arrived in America. Most 4, historians believe that they came to North America from Asia around 12,000 BC. They were probably walking along an overpass that crossed the Bering Strait. The overpass would have been formed times during the Ice Age. At that time, the sea level had fallen times and the land was exposed. Most scholars accept the overpass theory to explain how the first people came to America. However, some scientists today challenge this theory. They think the first Americans could have sailed earlier, perhaps by sea.
