Answer:
Adelle’s attitudes and behaviors are most consistent with the post-conventional stage of moral development.
Explanation:
According to Kohlberg's theory of moral development, there are three stages of moral development. They are the pre-conventional, conventional and post-conventional stages.
Adelle's behavior is consistent with the post-conventional stage. In this stage a person develops his/her own sense of morality and make conscious decisions, not just relying on what the society believes to be right or wrong.
