B. Is a true answer. It would make sense, but this is a question thrown in to make you confused.
C. This is not true! Neither story has a magic helper in it!
D. This is not true. Its been awhile, but I think Kaddo's dies, but the main character in The story of Bada and Abdalla does not.
A. Is your answer. Think about it. Kaddo wanted to have everything for himself and when it came time when it was needed he wouldn't give it and his greed lead him to some bad affects of that decision. It is the same in the other story.
I hope that helps!
