Step-by-step explanation:
According to Freud, when a person's superego gets out of control: D. The person becomes overly rigid in conforming to society's rules. Freud's structural model of the psyche includes the superego, which represents the internalized moral and societal standards. When the superego becomes overly dominant or unchecked, it can lead to a state of hyper-conformity. In this scenario, the individual may become excessively rigid and strict in adhering to societal rules and norms. This can result in a personality characterized by moralistic attitudes, perfectionism, and an exaggerated emphasis on conforming to external expectations, potentially hindering flexibility and adaptability in navigating social situations.
