Julianne tells on her friend Zoe for cheating on an exam because Julianne believes that all students should follow the rules set by their school. In which stage of moral development would Kholberg place Julianne?

Obedience-and-Punishment Orientation is the correct answer.

Explanation:

Lawrence Kohlberg was an American psychologist who studied and expanded Jean Piaget's studies related to moral in children. He set the Stages of Moral Development as three, with two stages each: preconventional, conventional, and postconventional.

In the first part, the two stages are Obedience-and-Punish and Instrumental Orientation. The first one refers to avoid being punished by doing something illegal or incorrect, so children follow the rules. In the sentence, we can see that Zoe is cheating on her exam (illegal behavior) and her friend Julianne tells somebody in a position of authority (the teacher, here) what is happening. Since there is a punishment, the actions seems morally wrong for Julianne.
