Describing autism and subsequently labeling children under this category continues to be complicated.

The reason for this is that
A. autistic characteristics exist with many other known conditions and vary considerably across individuals.
B. autism is a social category that shifts in dimensions as our culture shifts.
C. the cause of autism is known but expensive to diagnose.
D. autism is a catch-all term for children who have no other diagnosis.

my answer is a.

I agree.

You are correct! The reason why describing autism and categorizing children under this category continues to be complicated is because autistic characteristics coexist with many other known conditions and these characteristics can vary considerably across individuals. This means that each person with autism may experience different symptoms and challenges, making it difficult to create a single, comprehensive description or label. Autism is a spectrum disorder, which means that it can manifest in a wide range of ways and with varying degrees of severity. Therefore, it is important to approach autism as a diverse and complex condition that impacts individuals differently.
