C. Here is a tall bold slugger set vivid against the little soft cities;
Explanation:
The poem "Chicago" by Carl Sandburg elaborates the city with a sense of pride and personifies it with using words like "Tool maker", "Stacker of Wheat", "Hog Butcher" and many more. He further goes on to describe the city life and the metaphor that he used in the poem out of these options is "tall bold slugger" as he compares the man to it. <em>As we know, a metaphor is employed to symbolize the meaning and similarly, this metaphor signifies and accomplishes the poet's aim to glorify the energy of the American working class. Thus, the option C is correct.</em>
