The Emancipation Proclamation freed
A most enslaved people in the South and North.
B all enslaved people in the United States.
C most enslaved people in the North and in border states.
D enslaved people in the South but not in border states.

C

Explanation:

The Emancipation Proclamation was more of a suggestion than anything, it did NOT free slaves in the South. That is a common misconception. What it did do was give hope to slaves in the South and free SOME slaves in the North and border states.

You can also use the process of elimination here: It's not A. because the Southern slaves were not freed.  It's not B., because once again Southern slaves were not freed. You do that until you get through all answers.
