What is a developmental disorder characterized by impairment in social interactions and communication?

The correct response is based on the specific characteristics that define the disorder in question. Autism is indeed a developmental disorder that primarily affects social interactions and communication skills. Individuals with autism may have difficulty understanding social cues, engaging in typical forms of communication, and forming relationships, which sets it apart from other disorders.

In contrast, attention-deficit hyperactivity disorder (ADHD) primarily impacts attention and hyperactivity levels and does not specifically focus on communication or social interaction impairments. Schizophrenia is a more complex mental health condition that involves a range of cognitive, behavioral, and emotional symptoms but is not classified as a developmental disorder. Similarly, obsessive-compulsive disorder (OCD) involves recurrent thoughts and behaviors but does not center around the impairments in social interaction and communication typical of autism.

Therefore, the defining features of autism distinctly align with the question, confirming it as the accurate choice.
