What happened as a result of the Columbian Exchange? A.) Millions of European people arrived in the Americas within 50 years.

B.) Most Native Americans converted to Christianity and a European way of life in the first century after contact.

C.) Plants, animals, people, and diseases moved between hemispheres with enormous consequences.

D.) The introduction of American varieties of potatoes, tomatoes, and other crops killed the European versions of those plants.

The best answer would be C. Is it multiple choice or select all that apply? My number one choice would be C.

Explanation:

New foods did not kill European "versions" (D is wrong).

A lot of natives stuck with their own religions and cultures.

There were plenty of Europeans that traveled to the Americas but it took a bit longer than 50 years to bring more than millions.

The best answer is C because I know that plants, animals, and diseases between the two hemispheres had a detrimental yet positive impact at the same time. More variety, but the diseases harmed many at the same time. Choose C.
