Which of the following is a common behavioral sign of autism in children?

Difficulty in social interaction is a common behavioral sign of autism in children. This characteristic can manifest in various ways, such as challenges in understanding social cues, difficulty in making or maintaining friendships, and issues with reciprocal communication. Children on the autism spectrum may struggle with initiating conversations, responding appropriately in social settings, and may seem disinterested in engaging with peers.

In contrast, excessive verbal communication, high levels of eye contact, and strong interest in group activities are not typical traits associated with autism. Children with autism often exhibit more restricted or atypical communication patterns, may avoid eye contact as a way of coping with sensory overload or social discomfort, and may have limited interest in group activities or play, preferring solitary or repetitive play instead.
