Answer:
B. free verse
Explanation:
Open form, also referred to as free verse, does not follow a fixed pattern of rhyme, rhythm, or line length. It allows the poet flexibility in how the poem is composed.
Other Answers:
Lyric, narrative, and descriptive are all poetic styles, so when it comes to this question, options C, D, and E can be eliminated because it is asking for the form.
Blank verse is another poetic form and is written in non-rhyming lines of iambic pentameter. This answer does not apply to the poem.
