Final answer:
The ego, as described by Freud, is guided by the reality principle, balancing the id's primal urges with the moral standards of the superego while maintaining a grasp on real-world constraints.
Step-by-step explanation:
According to Freud, the ego is governed by the c. reality principle. In Freud's theory, the ego's primary function is to mediate between the desires of the id and the restrictions of the superego. The id is driven by the pleasure principle, seeking immediate gratification of its impulses, while the superego represents the moral ideals and social norms we internalize from our environment. The ego must navigate these opposing forces within the bounds of reality, making sure that the desires of the id are fulfilled in ways that are socially acceptable and realistic, thereby avoiding negative emotions like guilt and anxiety. This balance is crucial for a healthy personality, and imbalances can lead to neurosis or other psychological issues.
