Final answer:
To make the sentence about Prader-Willi Syndrome accurate, the name 'Prader-Willi syndrome' needs to be changed to 'Autism Spectrum Disorder' to reflect the correct disorder associated with repetitive behaviors and communication and social problems.
Step-by-step explanation:
The modification needed to render the sentence about Prader-Willi syndrome accurate is A. Change the name 'Prader-Willi syndrome' to the name 'Autism Spectrum Disorder'. The sentence as given describes characteristics such as repetitive behaviors and communication and social problems, which are indicative of Autism Spectrum Disorder (ASD), not Prader-Willi Syndrome (PWS). PWS is indeed a genetic disorder, but it is mainly characterized by persistent hunger, obesity in childhood, and emotional problems. ASD, on the other hand, includes deficits in social interaction, communication abilities, and engagement in repetitive behaviors.
