According to Freudian theory, an individual who is guided only by pleasure, has no internalized social rules of behaviour, and has little ability to balance the id with reality demonstates an:

Correct option is B

In Freud's structural model of personality, the id operates entirely on the pleasure principle, seeking immediate gratification without concern for reality or social norms. An overdeveloped or dominant id, with weak ego and superego development, would result in an individual who is impulsive, seeks immediate pleasure, lacks internalized moral standards, and cannot effectively mediate between desires and reality. This represents a personality structure dominated by primitive drives without adequate reality testing or moral constraints.

Information Booster:
1. Id Characteristics: Completely unconscious, present from birth, operates on pleasure principle, contains libidinal and aggressive drives
2. Lack of Reality Testing: An overdeveloped id overwhelms the ego's reality-testing function, leading to impulsive and potentially destructive behavior
3. Absent Moral Constraints: Without adequate superego development, there are no internalized parental or social values to constrain id impulses
4. Developmental Failure: Suggests developmental arrest or regression where ego and superego failed to adequately develop or have been overwhelmed
5. Clinical Manifestations: May appear as impulse control disorders, antisocial behavior, or primitive personality organization
