Which of the following is NOT a Cluster B personality disorder?

• A. Histrionic personality
• B. Borderline personality
• C. Antisocial personality
• D. Schizoid personality

Answer: (D)

In DSM classification, personality disorders are grouped into clusters by the pattern of traits they share. Cluster B includes dramatic, emotional, and erratic patterns, specifically antisocial, borderline, histrionic, and narcissistic types. Schizoid personality stands apart with a pattern of social detachment and a limited range of emotional expression, which aligns with Cluster A rather than Cluster B. So schizoid personality is not in Cluster B, making it the correct choice for the item asking which is NOT a Cluster B disorder.
