The correct answer is A. From C to A.
Explanation
The map shows the Atlantic Ocean and part of the continents of America, Europe, and Africa. Each of the continents is referenced with a letter as follows: Europe with the letter B, America with the letter A and Africa with the letter C. In addition, the oceanic trade routes between the three continents are shown.
This commercial relationship between the three continents had a specific dynamic because each one played a fundamental role. Slaves were transported from Africa to the American colonies to work in crops and mines. The natural resources obtained in America were brought to Europe to be converted into objects such as clothing and jewelry. Later, some objects were taken to America to be sold in exchange for gold coins. According to the above, the correct answer is A. because the slaves were taken from Africa (letter C) to America (letter A).
