Verified step by step guidance

1. Step 1: Understand that Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by challenges in social communication and interaction, as well as restricted and repetitive behaviors.
2. Step 2: Review the options given and identify which symptoms align with ASD characteristics. For example, compulsive hand washing and checking behaviors are more typical of Obsessive-Compulsive Disorder (OCD).
3. Step 3: Recognize that recurrent episodes of mania and depression are hallmark features of Bipolar Disorder, not ASD.
4. Step 4: Note that persistent delusions and hallucinations are symptoms commonly associated with Schizophrenia or other psychotic disorders, not ASD.
5. Step 5: Conclude that the primary characteristic of ASD among the options is difficulties with social communication and interaction, which is central to the diagnosis.
