During the Civil War, the South’s use of enslaved labor gave it a way to keep plantations running (Option "C" is the correct one).
Enslaved African Americans, who lived in the South of the US, responded to the American Civil War (1861–1865) in a variety of ways. Some slaves assisted the Confederate war effort, while others were forced to support the Confederacy by working on farms or plantations, in factories and households. There were many slaves who could escape and earn their freedom. Those slaves who remained on their plantations and farms worked as agricultural laborers while their production helped feed both civilians and soldiers. However, much of the wartime agricultural work in the South was carried out by female slaves, since males slaves were hired for the Confederacy's military and industrial works.
The correct answer is it lacked a bill of rights for the people.
This fight for a bill of rights for the people was lead by a group known as the Anti-federalists. The Anti-federalists feared that the new constitution did not guarantee a certain set of rights to citizens. This groups fear was that without this list of rights, the central (aka federal) government may become tyrannical and take away rights from citizens. This fear was rooted in America's experience as colonists under the control of Great Britain.
This is why the US Constitution ended up with a bill of rights, as Anti-federalists refused to agree to it until one was implemented.
