Which sequence of European countries first colonized America followed by others is correct?

The correct sequence is based on the historical timeline of colonization in the Americas. Spain and Portugal were the first European countries to establish colonies in the Americas, following Christopher Columbus's voyage in 1492, which was sponsored by Spain. The Treaty of Tordesillas, signed in 1494, divided the New World primarily between these two nations, with Spain focusing on much of South and Central America, while Portugal had influence in Brazil.

Following the initial colonization by the Spanish and Portuguese, the French began to explore and establish their presence in North America during the early 17th century, focusing on areas like Canada and the Mississippi River region. The Dutch also made their mark around this time, establishing settlements in present-day New York. Finally, the English began their colonization efforts with Jamestown in 1607 and continued to expand in the following decades.

This chronological understanding supports the answer that outlines the initial colonizers as Spanish and Portuguese, followed chronologically by the French and Dutch, and then the English, accurately reflecting the order of European colonial ventures in the New World.
