Explanation:

Lawrence Kohlberg states that there are three stages of moral development which are; preconventional, conventional, and post-conventional stages.

He explains that as children grow, they move from the preconventional stage (where they accept rules imposed by authority figures), to the conventional stage (where they still follow rules in order to maintain order in the society), and finally to the post-conventional stage (where they reject certain rules as being unfair and try to get rid of them).

However, NOT everyone reaches the post-conventional stage of moral development.
