A. Corn and tomatoes were introduced to Europe from America.

To determine which choice best illustrates the process known as the Columbian Exchange, we need to understand what the Columbian Exchange actually refers to. The Columbian Exchange was the widespread transfer of plants, animals, culture, human populations, technology, and ideas between the Americas and the Old World (Europe, Africa, and Asia) following Christopher Columbus' first voyage to the Americas in 1492.

Now, let's analyze each of the answer choices and determine which one best fits the description of the Columbian Exchange:

A. Corn and tomatoes were introduced to Europe from America: This answer choice accurately describes one aspect of the Columbian Exchange—introducing new plants from the Americas to Europe.

B. Christopher Columbus sailed west to reach Asia and encountered Native Americans: While this answer choice is historically significant as it describes Columbus' voyage and his encounter with Native Americans, it does not directly address the process of the Columbian Exchange.

C. Asian goods moved long distances along the Silk Road to reach Europe: This answer choice refers to the Silk Road trade routes between Asia and Europe, which is different from the Columbian Exchange.

D. Advances in technology allowed sailors to better navigate on the open seas: Although technological advances in navigation, such as improved maps, compasses, and ships, were crucial for the age of exploration, this answer choice does not directly relate to the process of the Columbian Exchange.

Based on this analysis, we can conclude that the best answer choice that illustrates the process known as the Columbian Exchange is A. Corn and tomatoes were introduced to Europe from America.
