The poem Forgetfulness by Billy Collins is a very particular poem, it does not rhyme, it has a free verse structure, meaning that it doesn´t actually have an organization on the stanzas, nor has a certain amount of syllables in each stanza, and it ends in a 4 verse paragraph, which means that it doesn´t end with a couplet, so the only one that would be true from the options would be the fact that it does not rhyme.
