Explanation:

The correct answer is the following.

The correct chronological order is:

1) Christopher Columbus sets out on his first voyage

2) the Muscovy company is established.

3) the Spanish established their first settlement in North America

4) the French established a fur trade in Canada.

We are talking about colonial times in the Americas. With the sponsorship of King Ferdinand of Aragón and Queen Isabelle de Castille, Christopher Columbus set his voyage and discovered America on October 12, 1492. From there, most European superpowers decided to send explorations, conquerors, and colonizers to the new territories. The English established the 13 colonies in North America, the French were more interested in the Fur trade with the Native Americans, and the Spaniards conquered the Aztec Empire and the Inca Empire.
