Which of these is an accurate comparison of the results of the columbian exchange?

There are no options from chose to but I will explain the overall results of the Colombian exchange:
The Exchange was a transfer of livestock, plantation, culture, technology etc. on a very large scale between Americas and the Old World. From this exchange Native Americans suffered more damage although there were benefits for Europeans and Native Americans both. Europeans gained a large amount of resources from this exchange while Native Americans suffered some persecution and fatalities as well.
