Answer: Postconventional.
Explanation:
According to Kohlberg, in the Postconventional Level of moral reasoning is as far as people can go, and only around 15% are able to develop the abstract thinking required. In this level, self-chosen principles determine personal judgment, while individual rights and justice are the foundation for their moral reasoning. Most people build their moral beliefs based on people they know, whereas a small minority will develop their own ethical principles.
