Counselors should select treatment strategies and interventions that are:

A) Capable of producing change for the client
B) Empirically sound
C) Research-based
D) All of the above

Counselors should select treatment strategies and interventions that are capable of producing change for the client, empirically sound, and research-based. This ensures that the interventions are effective, backed by research evidence, and can bring positive change to the client's life. Choosing interventions solely based on personal preference or intuition may not provide the best outcomes. Therefore, it is recommended to choose interventions that encompass all three criteria.
