Europeans turned to africa as a source of enslaved persons because

there weren’t enough criminals and captives to do the work.
groups of american indians were exploited and decimated.
only africans were capable of doing the backbreaking work.
only africa could provide the number of workers needed.

"there weren’t enough criminals and captives to do the work." is wrong, because the European didn't enslave their criminals.

"only Africans were capable of doing the backbreaking work." there's nothing to prove that this was the case

"only Africa could provide the number of workers needed." this is also not the case. Since there were plenty natives.

The answer is:

"groups of American Indians were exploited and decimated."

In the end, the Africans did not die as much as the Indians. So the Europeans had a source, the slaves could handle the diseases and wouldn't die as much.

"groups of American Indians were exploited and decimated."
