Verified step by step guidance

1. Step 1: Understand the core characteristics of Autism Spectrum Disorder (ASD). ASD is primarily characterized by difficulties in social communication and interaction, as well as restricted and repetitive patterns of behavior, interests, or activities.
2. Step 2: Review each option in the context of ASD symptoms. 'Impaired social communication' is a hallmark feature of ASD, involving challenges in understanding and using verbal and nonverbal communication.
3. Step 3: 'Restricted and repetitive behaviors' are also a core symptom of ASD, including repetitive movements, insistence on sameness, and highly focused interests.
4. Step 4: 'Difficulty with nonverbal communication' is part of the social communication challenges seen in ASD, such as trouble interpreting gestures, facial expressions, or body language.
5. Step 5: 'Hallucinations and delusions' are not associated with ASD; these symptoms are typically linked to psychotic disorders like schizophrenia, not autism.
