D. It begins with comparisons of the other and shifts to comparisons of speaker.
Explanation:
The tone of the poem "Litany" by Billy Collins is ambiguous and doesn't follow a complex syntax or structure. So, the second option goes wrong. The third and fourth suggests the usage of hyperbole and the poet has used metaphors. So, all three becomes incorrect except the first one that suggests the comparisons made by the speaker. The entire poem is based on comparisons using different metaphors like 'bread', 'knife', 'goblet', 'wine' 'birds in flight', 'pine-scented air', etc. The poet begins with the comparison of his beloved and concludes with the comparison of the speaker himself to different metaphors like he says "I am also the moon in the tree and blind woman's teacup".
