The correct answer is option E.
William Glasser was a well-known psychiatrist or reality therapist. He claimed that the underlying problem of most clients is almost same, which is either they are involved in a dissatisfying relationship or lack what could even be called a relationship.
It majorly occurs because of their inability to connect with others, or to have a satisfying or healthy relationship with at least one significant person present in their lives. The role of therapists in these cases is to teach them to behave in more effective ways than they are presently behaving. The more clients are able to connect with people, the greater chance they have to experience happiness.
