Hello,
The answer is option D "tone".
Reason:
Tone is really important in any writing (but would be important in a poem) it gives the reader a mood could be sad, happy, angry, etc... Also its not option A because some poems dont rhythm. Its also not option B because volume would be with tone which means the character is raising their voice as such its also not option C because accuracy always matters but some poems are difficult to understand therefore the answer should be option D!
If you need anymore help feel free to ask me!
Hope this helps!
