A child has difficulty going to school alone and being in a room by himself/herself. He/she fears entering new situations and clings to his/her parents. These symptoms are indicative of:

Separation anxiety disorder

The correct answer is Option (2) → Separation anxiety disorder

Separation anxiety disorder (SAD) is another type of anxiety disorder. Individuals with separation anxiety disorder are fearful and anxious about separation from attachment figures to an extent that is developmentally not appropriate. Children with SAD may have difficulty being in a room by themselves, going to school alone, are fearful of entering new situations, and cling to and shadow their parents’ every move. To avoid separation, children with SAD may fuss, scream, throw severe tantrums, or make suicidal gesture.
