Concept:Kohlberg’s theory proposes that moral reasoning develops through a fixed sequence of stages, each building on the previous one.Explanation:Kohlberg argued that moral development is not continuous or random. Instead, it happens in distinct, progressive stages. Children move step by step from simple ideas of right and wrong to complex ethical principles. Each stage must be mastered before moving to the next. This order is universal and hierarchical. Kohlberg did not focus on gender or cultural differences in moral reasoning; his core claim is about stage-wise progression.Answer:D. moral development occurs progressively in stages.
