The correct answer is A. Why the emotional pain of oppression makes the caged bird shout
Step-by-step explanation:
The poem presented in the question is divided into two main stanzas one that describes the free birds and another describing the caged birds. In the case of the first stanza, the author describes the way the free bird thinks about the breeze, the wind, and the worms and the way the bird own the sky. On the opposite, the second stanza describes the caged bird as sad, tormented and unable to scape as in "stands on the grave of dreams" or "his wings are clipped and his feet are tied", and the author finally explains because of this feelings "he opens his throat to sing", this shows a contrast between both birds, especially in the oppression of the caged bird and the way this shouts or sings due to this oppression. Therefore, after reading both stanzas the reader can understand "why the emotional pain of oppression makes the caged bird shout".
