Answer:According to Kohlberg's theory of gender-role development, the answer is (C) have achieved gender constancy.
Step-by-step explanation:
Gender constancy is the third and final stage in Kohlberg's theory of gender development. It typically occurs around the age of 6 or 7. At this stage, children understand that their gender is stable and consistent over time, regardless of superficial changes in appearance or behavior. They realize that being a boy or a girl is not something that can be easily changed.
Once children have achieved gender constancy, they are more likely to seek out and imitate same-sex models (people of the same gender) because they have a clearer understanding of their own gender identity and the gender roles associated with it. So, this is the stage at which children are more inclined to imitate and conform to the behaviors and roles associated with their own gender.
