The correct answer is A, Lincoln: birth of freedom, King: righteousness' sake.
Lincoln said "birth of freedom" to help the nation come to terms with the end of slavery and define the meaning of freedom.
Righteousness is defined as the quality of being morally right or justified.
Both of these phrases best support the theme of equality for all, because they show that freedom is for all and that the morally right thing is that everyone is treated equal.
it is basically the same thing just one is more proper than the other. Kind of like how people in the south speak one way and people from the north speak totally different.
