The correct answer is D. Africans tended the settlers' land and harvested crops.

Explanation:

One of the factors that supported slavery and indentured servitude in North America during the colonization, and even after it was that slaves and servants were essential for colonies. This is because servants and Africans used as slaves were in charge of settlers' land and growing crops, which supported the economy of that time. Indeed, settlers earned profit from products such as cotton or tobacco due to the use of slaves or servants, and this also made colonies thrive. In this context, a detail that supports the idea slaves and servants were essential for colonies is "Africans tended the settlers' land and harvested crops".
