Answer:
D). Preconventional reasoning.
Step-by-step explanation:
Preconventional reasoning is characterized as the initial stage of the moral development theory proposed by Kohlberg. In this stage, the children tend to display obedience to the rules and acceptance towards the teachings of the authority figures as they are not yet been able to reason or internalize these things themselves.
As per the given description, Megan is in 'preconventional' level of moral development(according to Kohlberg's theory) as she displays obedience and conformity to the rules set by her mother(which represents the 'authority figure') to avoid punishment. Thus, option D is the correct answer.
