In the Seventeenth- and Eighteenth-Century American Colonies, How Did Indentured

In the seventeenth- and eighteenth-century American colonies, how did indentured servitude and race-based slavery evolve in relation to each other?

A) As Enlightenment ideas spread about the evilness of race-based slavery, the number of enslaved Africans in America declined, and the number of European indentured servants gradually rose to compensate.
B) As commercial agriculture grew, the colonists came to prefer the labor of enslaved Native Americans to that of enslaved Africans or indentured servants due to their familiarity with American crops.
C) After 1700, most new immigrants coming to the Americas were English rather than African, so English indentured servants were given the bulk of the agricultural labor in the South.
D) As the sugar, tobacco, rice, and indigo economies expanded and demanded harsher, more intensive labor, the number of enslaved Africans grew and the number of European indentured servants slowed.
E) Because the original Africans of the Americas had come to have children who were also enslaved, the colonists no longer maintained slave-trading companies, and indentured servitude became obsolete.
