The direct result of the Columbian Exchange was D. Europeans spread diseases to American Indians. This exchange occurred after Christopher Columbus arrived in the Americas in 1492 and opened up a widespread exchange of goods, ideas, and diseases between the New World and the Old World. European diseases, such as smallpox, measles, and influenza, were introduced to the Americas, causing devastating epidemics among the indigenous populations who had no immunity to these diseases. This led to a significant decline in the American Indian populations in the years following the Columbian Exchange.
