Which of the following is classified as a developmental disability?

The classification of intellectual disabilities as a developmental disability is correct due to the developmental nature of the condition, which typically manifests in childhood and affects functioning in multiple areas, including cognitive abilities, social skills, and daily living activities. Intellectual disabilities are characterized by significant limitations in intellectual functioning and adaptive behavior, which emerge during the developmental period (before the age of 18). This classification aligns with standards set by organizations such as the American Association on Intellectual and Developmental Disabilities (AAIDD) and the Diagnostic and Statistical Manual of Mental Disorders (DSM).

Other options, while they represent various developmental challenges or disorders, do not fall under the same criteria. Speech delay, for instance, can be a symptom of various issues but does not necessarily equate to a broader developmental disability in the same way intellectual disabilities do. Anxiety disorder is classified as a mental health condition rather than a developmental disability and typically pertains to emotional regulation rather than cognitive or adaptive functioning. ADHD, or Attention-Deficit/Hyperactivity Disorder, is recognized as a neurodevelopmental disorder but does not encompass the significant cognitive limitations and broader adaptive behavior impairments seen in intellectual disabilities.
