The answer is B) an enslaved person was defined as someone who could be bought and sold.
During the 1600's, slaves were considered property not people thanks to slave codes. These laws gave slaves no legal rights, ensuring that white slave owners could treat slaves however they wanted. This resulted in long working hours, harsh working conditions, and possible physical punishment for not accomplishing certain tasks. This legal status as property would remain well into the middle of the 19th century, as the Dred Scott vs. Sandford case reiterated this legal status of slaves.
