I believe the answer is A
In the Emancipation Proclamation, issued by the President of the United States, Abraham Lincoln, in the year of our Lord 1863, "suitable condition" refers to option 3. that those persons who were previously enslaved must have displayed the same minimum requirements for service in the armed forces as those who had not been enslaved.
In the Emancipation Proclamation, President Lincoln, states that " ...I do order and declare that all persons held as slaves within said designated States, and parts of States, are, and henceforward shall be free..." and those who are in good condition to serve the armed forces of the United States will be received there.
All of them but 'Person vs. Self'
