Answer:
Option a (unrhymed iambic pentameter) is the correct choice.
Step-by-step explanation:
- There seems to be no rhyme scheme and therefore no set metrical sequence in the free-verse literature.
- A free-verse piece frequently follows the inflections of human speech which makes imaginative use through tone, imagination as well as a huge assortment of language techniques.
Some other choices presented are not concerning the situation in question. So choice a is the right answer to that.
