In order to be able to answer this, we'd need to know what book it is you're reading, as well as the answer choices as the question asks "which of the following best" meaning that they want you to choose the best answer from the choices they’re giving you.
Fuzzy because it follows the linking verb(((:
Dear sir or ma'am, (if a name is given use a name) or just begin with Hello,
I received an overdue notice about ___________(book) but I know I returned the book to you on _____ (date) because I have a receipt of return with that book listed on it.
I hope this will clear up any confusion and they charge will be removed from my account
Thank you,
(Your name)
I would just explain to them how poetry is a way of writing in order to capture physical and emotional details unable to be written in factual writing. Hope this helps :-)
