C. Libido
D. Superego
Answer: B. Ego
Explanation: According to Freud, the ego is the part of the mind that is in charge of the balance between selfish ID and moral superego. As stated, satisfying basic needs involves satisfying ID, while adapting to the demands of the real world is what makes us moral, therefore, a superego. Meeting and adapting to the needs of the real world means setting moral principles out of the knowledge that we are not alone, and we cannot be selfish, while ID persistently requires meeting those basic needs, and that is also natural. The ego is the one that balances.
The ego develops very early, after the initial period of the child's life, according to Freud. During this initial period, which is ID, the primary part of the personality, develops. During initial ID, through crying, the child requires the satisfaction of his hunger, thirst, crying when wet, etc., in order for the ego to start developing between the ages of three and five. Then the child begins in a different way to demand that his needs be met. The kid realises that crying is not going to get anything and starts looking for what s / he wants more "diplomatically".
