The understanding that gender is permanent is called

A) social learning.
B) observational learning.
C) gender constancy.
D) gender segregation.

Gender constancy refers to the understanding that one's gender is a stable and permanent characteristic, regardless of superficial changes in appearance or behavior. This means that a child with gender constancy would understand that a person who dresses in clothing typically associated with the opposite gender is still the same gender they were before, and that gender is not something that can be changed. Social learning and observational learning refer to the ways that children learn about gender roles and expectations, while gender segregation refers to the tendency of children to prefer same-gender playmates.
