Slaves were brought into North and South America and forced into
A. free labor on the large plantations
B. paid labor on numerous plantations
C. free domestic labor throughout the colonies

A. free labor on the large plantations.

Explanation:

B. paid labor on numerous plantations is incorrect because the definition of the word slave states that a slave is a person that is the legal property of another and is forced to obey them. If that were the case, then their owners would have no need to pay them.

C. free domestic labor throughout the colonies is incorrect because bringing slaves from African countries into North and South America was very expensive and time consuming, so it would be a waste of time and resources to force the slaves to do things that didn't directly contribute to the profession of their owners.

Therefore, the answer must be A. free labor on the large plantations.
