Answer:
The correct answer is letter D. blank verse.
Explanation:
The excerpt shown in the picture belongs to the poem Ulysses by Alfred Lord Tennyson. The option that best describes the structure is letter D. blank verse.
Free verse happens when a poem does not follow any rules for meter or rhyme schemes. This poem, however, does follow a rule for meter: iambic pentameter - a five-time repetition of an unstressed syllable followed by a stressed one.
A sonnet follows pretty strict rules. It has 14 lines written with iambic pentameter, and it has a specific rhyme scheme. As we can see in the excerpt, the lines in this poem do not rhyme.
A ballad is usually divided into quatrains. It presents an abab rhyme scheme. Thus, this poem is not a ballad.
The only option left - and the correct one - is blank verse. Blank verse happens when the lines do not rhyme, but they do present a regular metrical - usually, iambic pentameter. That is precisely what happens in this poem.
