Answer:
A. Because each word acts in relationship with others to achieve the overall effect.
Step-by-step explanation:
Option A is the correct answer.
This is true because in poetry, words are very very important. Without words, poems cannot be written and conveyed. Therefore, in order for their poems to have an overall effect, poets pay attention to the ordering of their words. That is why features of poems like alliteration, imagery, etc. are used in order to convey meaning and themes.
In choosing of words, sometimes poets do that for the way the words sound and sometimes for their connotations.
