The correct answer is C. The Columbian Exchange was the movement of plants, animals, diseases, and people among continents as a result of European exploration.
Step-by-step explanation:
The Columbian exchange was an intercontinental biological exchange that occurred during the historical period of the European discovery of America by Christopher Columbus. It is one of the most important events in the history of ecology, agriculture and culture.
This term was coined by Alfred W. Crosby in 1972, designating the numerous exchanges in agricultural and livestock goods, in human populations and in microorganisms (particularly in microbes responsible for infectious diseases), starting in 1492, between the Old World and the New World as well as between the east and west hemispheres of the Earth.
