Research has shown that children with autism spectrum disorder (ASD) often experience unusually accelerated head and brain growth in the first few years of life, suggesting a neurodevelopmental basis for the disorder.

Answer: D
 While there is no single genetic mechanism that has been identified as causing ASD, research has shown that brain abnormalities are likely involved in the condition, providing further support for a neurodevelopmental basis.

Option A is not the best choice because overactivation in certain areas of the brain that are associated with facial recognition and the recognition of facial expressions is only one aspect of the neurodevelopmental basis of ASD. Option B is also not the best choice because low levels of specific neurotransmitters in children with the disorder are not consistently found in all individuals with ASD and therefore cannot be considered a definitive factor in the condition's neurodevelopmental basis.
