Hey!
I'm pretty sure answer is the last option
The caged bird is the African American, who is held in a sub-free state by the whites. The sky is freedom, for a bird, flying is the freest thing there is. The free bird is the white American, who's never had to be a slave or seen as subhuman. The cage is the Jim Crow laws that subvert the stated "freedom" of blacks at that time. Singing is self expression, that is one of the only things that slavery can't take from a person. Hope this helps!
