According to psychologists, the definition of abnormality has four features -

Deviance, Dysfunction, Danger, Distress

The correct answer is Option (2) → Deviance, Dysfunction, Danger, Distress

Although many definitions of abnormality have been used over the years, none has won universal acceptance. Still, most definitions have certain common features, often called the ‘four Ds’: deviance, distress, dysfunction and danger. That is, psychological disorders are deviant (different, extreme, unusual, even bizarre), distressing (unpleasant and upsetting to the person and to others), dysfunctional (interfering with the person’s ability to carry out daily activities in a constructive way), and possibly dangerous (to the person or to others).
