Answer: The right answer is the A) Ballad.
Explanation: Just to elaborate a little on the answer, it can be added that none of the other options are correct, since this poem has verses that rhyme and it has more than fourteen lines. This poem is a ballad, a narrative song that recounts a very tragic event — the death of four African American adolescents when their church in Birmingham, AL, was bombed on September 15, 1963. Apart from the narrative structure, it also features the characteristic repetition of lines, specifically the repetition of the line "And the choirs kept singing of Freedom."
