Verified Answer :

Slave codes affected enslaved people by "c. keeping them powerless" since this is how the slave owners and white society in general kept them as unpaid servants. 

The correct answer is:

C. Keeping them powerless

Explanation:

Slave codes were a set of laws and rules designed to protect slave owners from slave rebellions and to control slaves by enforcing numerous restrictions. Under slave codes, slaves were seen as property rather than persons.

Some of the restrictions enforced in slave codes were that they could not marry, they couldn't learn how to read or write, they could not assemble unless a white person was present, they couldn't own fire guns, and they couldn't defend themselves from an attack of a white person. This set of restrictions kept slaves powerless.

In the United States South Carolina was the first state to adopt the slave codes in 1691, followed by Georgia and Florida, by the start of the American Civil War all of the slave states had slave codes.
