Answer :
The definition most closely reflects the poem is sestina. option.D.
A sestina is the best option because it matches the poem's unique structure of six six-line stanzas followed by a three-line stanza, totaling 39 lines. Each stanza repeats the ending words from the first stanza in a specific order.
This repeating pattern and the use of the same six words in the final stanza are distinctive features of a sestina.
No other poetic form mentioned—sonnet, free verse, or haiku—has this complex pattern of repetition and specific structure, making the sestina the closest match to the described poem.
