In Kohlberg's theory of moral development,at the 6th and highest stage there is a ______.

A) strong desire to avoid punishment which motivates ethical behavior
B) concentration on internalized principles of ethics
C) strong norm of reciprocity
D) reliance on universal ethical principles of justice,reciprocity,etc.

According to Kohlberg's theory, at the highest stage of moral development (stage 6), individuals rely on universal ethical principles of justice, reciprocity, and a commitment to ethical values that transcend the law. This stage is characterized by a focus on abstract reasoning and principles rather than on personal feelings or social norms. Therefore, option D is the most appropriate choice. Option A focuses on an earlier stage of moral development where individuals are motivated by a desire to avoid punishment, which is not applicable to the highest stage. Option B also focuses on an earlier stage where individuals internalize rules and norms of their social group, rather than relying on universal ethical principles. Option C emphasizes the norm of reciprocity, which may be important in moral behavior, but it is not the only guiding principle at the highest stage of moral development.
