Hello, I found the excerpt from another source:
He was from Massachusetts, born near Chappaquiddick, this old flongboo, and he lived there in a horse chestnut tree six feet thick halfway between South Hadley and Northampton. And at night, before he lost his tail, he lighted up the big hollow cave inside the horse chestnut tree with his yellow torch of a tail.
Based on that excerpt, we can clearly see that Carl Sandburg utilized both imaginary animals and real places; therefore, among the four options, the one option that would be the BEST answer would be option B since Sandburg combined both elements.
ANSWER: B. combining imaginary animals and real places.
