Respuesta :

The option that does not describe the Columbian Exchange and its consequences would be "a. corn and potatoes as crops in the Americas for the first time," since in fact corn existed in the Americas before the arrival of Columbus. 

The correct answer is A. Corn and Potatoes as crops in the Americas for the first time
