Final answer:
Selective Mutism is the condition where a child cannot speak in specific situations, while b) Autism Spectrum Disorder includes a broader range of communication and behavioral issues.
Step-by-step explanation:
The condition described where a child is talkative at home but refuses to speak in select settings is indicative of Selective Mutism. Selective Mutism is an anxiety disorder where a child who is normally capable of speech is unable to speak in specific situations or to specific people. This is different from Autism Spectrum Disorder (ASD), which involves a broader range of social communication deficits and repetitive behaviors.
When assessing impaired social skills, such as difficulty in making eye contact or reading social cues, one possible condition that professionals might test for is Autism Spectrum Disorder. Children with ASD also show a variety of other symptoms, including repetitive motor behaviors, strict adherence to rituals, and a preoccupation with specific subjects. While the social challenges might appear similar in Selective Mutism and ASD, the contexts and other associated symptoms can help differentiate between the two disorders. The correct answer is option b.
