Cynthia's Daughter Has Asperger's Disorder

Cynthia's daughter has Asperger's disorder. Cynthia explains that people must use person-first language when referring to children with autism. What does she mean by this?

A) Use the phrase "child with autism" rather than using the term autism to define the child (e.g., "the autistic child") .
B) Do not refer to a child's social deficiencies or stereotyped behaviours in any way because it makes people uncomfortable.
C) Ignore the symptoms when speaking of the child's autism so that the child maintains a positive self-image.
D) Treat the child according to their behavioural age rather than the their chronological age in years.
