Answer:
It would be B.
Explanation:
Well, a claim is a line that tells you straightly which side of an argument your on.
B imediately tells you the person wants to change the rules, it doesn't say "Their are several advantages" because you don't say that to make it effective and also you shouldn't use opinion because others will have a different opinion.
Usually, try avoiding opinions where they are more than 2 outcomes. Only try going for 2. This makes it so that their is a limit of answers so you don't have to list them all.
Usually their is only more than one outcome when finding the theme of a short story or novel.
