Answer:
The correct answer is option C. It is a thetorical question that shows the speaker's exasperation.
Step-by-step explanation:
This question refers to the poem written by Lawrence Raab.
The final question says: What are they doing, writing all this again?
This question is rhetorical, the speaker asks in exasperation why he continues to write poems for his beloved? If he has already made it clear that they have separated.
The problem the speaker has is that he misses someone he loves very much, hence his frustration. And instead of letting her go, he continues to write poems.
