Which statement correctly lists the typical personality disorders by DSM clusters A, B, and C?

• A. Cluster A: paranoid, schizoid, schizotypal; Cluster B: antisocial, dependent, avoidant, narcissistic; Cluster C: histrionic, obsessive-compulsive.
• B. Cluster A: paranoid, schizoid, schizotypal; Cluster B: antisocial, borderline, histrionic, narcissistic; Cluster C: avoidant, dependent, obsessive-compulsive.
• C. Cluster A: paranoid, dependent, avoidant; Cluster B: antisocial, narcissistic, histrionic; Cluster C: schizoid, schizotypal.
• D. Cluster A: paranoid, schizoid, schizotypal; Cluster B: antisocial, borderline, histrionic, narcissistic; Cluster C: avoidant, dependent, obsessive-compulsive.

Answer: (B)

DSM personality disorders are grouped into three clusters based on shared patterns of traits: odd/eccentric in the first cluster, dramatic/erratic in the second, and anxious/fearful in the third. The correct listing mirrors the DSM-5 organization: paranoid, schizoid, and schizotypal belong to the first cluster; antisocial, borderline, histrionic, and narcissistic belong to the second; avoidant, dependent, and obsessive-compulsive belong to the third. This alignment is why the statement is correct. Other options mix disorders across clusters (for example, placing dependent or avoidant in the dramatic/erratic cluster or pairing histrionic with the anxious/fearful cluster), which does not fit the DSM grouping. Also, note that obsessive-compulsive in this context refers to obsessive-compulsive personality disorder, not obsessive-compulsive disorder.
