I`ve read this book like 9 times, so i`ll take a gander and say it`s C. Smaug had promised it to him if he led him to the dwarves.
I think it’s B but they all kinda make no sense
Quotes, punctuation or descriptive words depending on the situation. (idk if this will help, need more context to fully understand the question)
Explanation:
I could not find the piece of evidence that is missing in your question but I will tell you some information about how to find it easier by yourself.
Evidence should have the facts and pieces of information that are supporting the beliefs or ideas. It should be proof of something right. For example, if we have an assignment where we must tell if some statement is true or falls, we must know the evidence and the proof for supporting our answer and what makes that answer right, what supports it.
So, for finding the best support for the answer to part two you must find the evidence that will be the most helpful one for solving it.
