Answer: It honestly depends on what kind of poem you are reading and how it's styled, but I'd narrow it down to A: Provide Closure
Explanation: Most of the time riddles arent involved or there isn't some huge question so C is out of the picture, Thanking the reader while not an unlikely thing to see in some poems, it is however not the most common kind of ending. Now we have it narrowed down to D and A, Now yes there are poems that echo the first line, though these poems aren't the most common (at least within my curriculem) as they are meant to usually change your outlook on something like society or certain group of a subject. So for a standard poem that is just trying to describe, explain, or emotionalize something through an artistic expression of the subject, I'd have to go with A.
Just remember that D is a viable option but I'm siding with A just to have a side that sounds most likely. As awlays I hope this helped and would appreciate a Brainliest if I am correct, Tschuss!
