The correct answer is A) Unlike Africans, Europeans wanted the adult males for hard work.
The other options of the question were B) Unlike Africans, Europeans saw slavery as a form of punishment for criminals. C) Unlike Europeans, Africans treated their slaves as property. D) Unlike Europeans, Africans did not let children of slaves go free.
The difference between African and European attitudes toward slaves was that unlike Africans, Europeans wanted the adult males for hard work.
That is why European colonists in the North America territory bough male African slaves to put them to work hard in the large plantations growing crops. These crops had to feed the colonist's families but also were exported to Europe for a profit. That is why the work in the farm fields was so demanding and needed strong people to do it.
