Using the system of elimination, I'd say the correct answer is C. It shows the worst of America, whereas the other poem shows the best of America.
It's not A because there is no love being portrayed in "I Sit and Look Out;" it's not B because there is no defined rhyme scheme in that poem; it's not D because both poems show the working class.
So based on this, it has to be C - the first poem shows hatred, pain, and violence, whereas the other one shows unity and love.
