Final answer:
In Kohlberg's theory, the sixth stage of moral development is best represented by Option 2: Social contract and individual rights, as it reflects the reasoning based on universal ethical principles and individual conscience. Option 2
Step-by-step explanation:
The deteminant of morality in the sixth stage of Kohlberg's theory of moral development, which is the last level of the postconventional level, is characterized by the recognition of universal ethical principles and abstract reasoning. This stage involves a moral reasoning that is based on abstract ethical principles that apply to all situations and societies.
Therefore, among the options provided, Option 2: Social contract and individual rights is the one that best represents the determinant of morality at this stage. People operating at the sixth stage of moral development make decisions based on ethical principles that transcend laws and social contracts when those are in conflict with individual rights and personal conscience.
Kohlberg's highest stage of moral development is markedly different from the other choices. Fear of punishment (Option 1), avoidance of physical harm (Option 3), and obedience to authority (Option 4) are all characteristic of the earlier stages of Kohlberg's theory; preconventional and conventional stages, rather than the principles-based postconventional stage 6. option 2
