What does research suggest about the comparative effectiveness of psychotherapeutic techniques? ch 16?

These are the choices I found on the internet:

a. A meta-analysis suggests that psychodynamic psychoanalysis is the least effective approach.

b. Data regarding the comparative effectiveness of psychotherapeutic techniques is unavailable.

c. No studies have found one psychotherapeutic approach more effective than another.

d. Research shows that cognitive-behavioral therapy is the most effective approach.

The answer is letter C - No studies have found one psychotherapeutic approach more effective than another.

it can either be 2. or 4. : ) tell me if i'm wrong or right

answer is:

a). backstage view

explanation:

backstage view is the area where files and data about them is managed— creating, saving, printing, sending to others, inspecting for hidden metadata or personal information, and setting options. so in this way we can add many things to our document swiftly.

i hope you get the idea.
