Which of the following is a characteristic of Autism Spectrum Disorder (ASD)?

The characteristic of Autism Spectrum Disorder (ASD) that is most prominently recognized is the challenges with social skills and communication. Individuals with ASD often find it difficult to understand social cues, engage in conversations, and make eye contact, which are essential components of effective communication.

They may struggle with various aspects of social interaction, such as initiating conversations, understanding non-verbal communication (like gestures and facial expressions), and forming relationships. These challenges can lead to misunderstandings in social settings and can significantly impact an individual's ability to navigate social environments.

The other options, while they may be present in some individuals, do not universally define autism. For example, high levels of physical activity and the inability to engage in imaginative play can vary widely among individuals with autism. Additionally, while some may experience difficulty understanding rules and boundaries, this is not a definitive trait of ASD and can be influenced by various factors, including age and cognitive ability. Thus, the correct answer emphasizes the core social and communication difficulties that are central to the diagnosis of Autism Spectrum Disorder.
