Final answer:
The result of the ego's failure to satisfy both id and superego is repression slipping into our conscious awareness. So, the correct answer is option b) Repression.
Step-by-step explanation:
The result of the ego's failure to satisfy both id and superego is repression slipping into our conscious awareness. Repression is a defense mechanism in which the ego pushes threatening or unacceptable thoughts, feelings, or memories into the unconscious mind, keeping them out of conscious awareness. It is important for the ego to repress these inner conflicts to maintain psychological stability. When the ego fails to do so, repressed thoughts or emotions might resurface and cause anxiety or distress.
