Final answer:
Simon is using preconventional morality.
Step-by-step explanation:
Preconventional morality is a concept in moral development theory, particularly associated with Lawrence Kohlberg's stages of moral development. Kohlberg outlined three levels of moral development, each with two sub-stages.
In this scenario, Simon is using preconventional morality. In Lawrence Kohlberg's theory of moral development, the preconventional stage is characterized by a focus on self-interest and avoiding punishment. Individuals at this stage tend to obey rules to avoid negative consequences. Simon obeys his parents' rules because he fears punishment if he doesn't, indicating that he is operating at the preconventional level.
