C. The other stories had males as the main character. D. The stories did not have a "happily ever after" ending.

B. The characters were always monsters.

Explanation:

L. Frank Baum had a very reclusive childhood, as he had health problems that prevented him from playing and having fun with other children. This made him spend his days at home and use reading for fun. At that time he was a big fan of fairy tales, but he was very critical that the characters in these stories were always showcases. That's because he ended up having terrible and frightening nightmares thinking about the creatures present in his readings. This provoked in him the desire to write a different fairy tale, where the characters would not be showcases, but companions, friendly and lovable and that is how "The Wonderful Wizard of Oz" appeared.

Therefore, we can say that L. Frank Baum did not like other stories like "The Wonderful Wizard of Oz" because the characters were monsters.
