Final answer:
Martin Luther King Jr.'s demonstrations, reflecting the belief that morality can transcend legal rules, illustrate Kohlberg's post-conventional level of moral development, which emphasizes principles and moral reasoning over societal laws. The correct option is d. Post-conventional morality
Step-by-step explanation:
Martin Luther King Jr. often broke the law during his demonstrations, which indicates he was operating at the post-conventional level of moral development according to Lawrence Kohlberg's theory.
This level is characterized by the belief that moral judgments must consider principles that have value and validity apart from people's opinions – principles that often transcend the established rules of society.
Individuals at this level, like King, recognize that legal and moral perspectives can diverge and that sometimes laws need to be disobeyed to uphold moral principles.
Martin Luther King Jr.'s civil disobedience was a reflection of such moral reasoning, seeking justice and equality which, in his view, transcended the written laws of the time. The correct option is d. Post-conventional morality
