Autism Spectrum Disorder features include which combination?

• A. Hyperactivity and aggression
• B. Normal social interaction
• C. Withdrawal into self with fantasy world, communication impairments, restricted repetitive behaviors
• D. Delayed language development

Answer: (C)

Autism Spectrum Disorder is defined by deficits in social communication and interaction, together with restricted and repetitive patterns of behavior, interests, or activities. The described combination—withdrawal into a self-contained or fantasy world, clear communication impairments, and restricted repetitive behaviors—embodies these defining features, showing both social-communication challenges and an insistence on sameness or narrow interests that can drive repetitive actions. While some individuals may exhibit hyperactivity or aggression, these are not the hallmark features of ASD. Normal social interaction would contradict the observed social-communication deficits, and delayed language development, though common in some cases, is not universal or exclusive to ASD. Recognizing this pattern guides early assessment and interventions, such as structured routines, tailored communication strategies, and multidisciplinary support to promote development and functioning.
