Answer:
C. Effects of the Columbian Exchange
Step-by-step explanation:
Columbian Exchange was widely referred to as an extensive exchange that occurred in the whole of America after the Christopher Columbus discovery of the continent. This massive exchange centers around human, technological, and socio-cultural ideas across the globe, which is majorly between the Americas, West Africa, and Europe starting in the late 15th century.
What was known as Columbia Exchange was caused as a result of Fertile, rich soil in the Americas. In addition to nearly all year-round growing season, there was a need for the increased demand for farm labor in America. Also due to ravaging diseases affecting white laborers, another set of laborers who were resistant to the diseases and cheaper were mostly gotten in West Africa as a form of slavery. This also put an end to indentured servant contracts that were common in British North America.
