If we're talking about ethos, pathos, or logos, the answer is ethos
Answer:
Dear {Friend Name},
Where do I even begin? I suppose saying “I’m sorry” is a start.
I’m sorry.
Looking back, I can’t believe that I {state offending action}. But I suppose hindsight is always 20/20. It was stupid and I wasn’t the friend that you expected me to be. Even if I explain my actions, it still doesn’t justify that I {said/did} some pretty hurtful things.
I hope you can forgive me for what I did and put this matter behind us. I treasure our friendship and all the things we’ve done and been through. And hopefully, what transpired can become one of those incidents that make our bond stronger than ever.
If you have anything on your mind regarding this, please feel free to share it. I promise to listen before I speak. It’s the least I could do if you’re willing to forgive me. You know how to contact me. I hope you do.
Your friend,
{Name}
Explanation:
The sentence which contains a properly punctuate and capitalized direct quotation is C. "Watch how that hummingbird flits from flower to flower," said Diane. Quotation marks always go around the dialogue when writing a direct quote. Capitalization rules still apply much in the same way as they do in regular sentence writing, in that you must capitalize the first letter of the first word at the beginning of a sentence. Punctuation that separates the quote from the speaker must be included with the quotation marks to show that there is a separation.
C or D look like the best answers. I would go with C personally, but don't credit me to this
