Did anybody ever answer this question?
Interesting. You did not describe the requirements, but the message seems good to me. Thanks for sharing.
Yes, the answer is definitely A - true. In the oral tradition, obviously, people didn't use written texts, they told their tales from memory. And of course they would add something, or remove something else, or use a different vocabulary from the person who told them that story. It cannot be told in the exact same way the previous person told it, it is impossible.
