What is the best evidence that this poem is written in free verse? It has two stanzas. It has no set meter. It uses alliteration. It has no repeating words.

B) It has no set meter.

Free verse poetry does not have a set meter or rhyme scheme. It has no specific structure. Free verse poetry can have as many stanzas as the poet chooses so this is not a deciding trait. Free verse poetry can also use figurative language such as alliteration, onomatopoeia, hyperbole, metaphor, simile, symbolism, etc. These do not make it free verse. The same goes for repetition. Repeating words does not make a free verse poem free verse or not free verse.
