Explanation:

ASM or Autism Spectrum disorder is a developmental problem in which the behavior and communication of an individual is badly effected. It can target a person of any age but because of its developmental age, people get effected by the age of only 2.

Diagnostic and Statistical Manual of Mental Disorders or DSM is a manual published by American Psychiatric Association that helps in the diagnosis of different mental disorders. The 5th version of this manual has been created and published called DSM5.

As mentioned in the question, the ASD is included in the manual of latest DSM 5, therefore, it is more easy for a therapist to diagnose and treat the disorder in an effective way.

Hope it help!

The correct answer is D. The therapist will be able to suggest appropriate treatment.

Explanation:

The Diagnostic and Statistical Manual of Mental Disorders (DSM) is a document that helps health care professionals to diagnose and treat different mental disorders. Indeed, this document acts as a guide by defining several mental disorders, its symptoms and possible alternatives for treatment. The last edition of this document is the fifth edition of DSM-5 published in 2013.

According to this, the fact autism spectrum disorder is included in the DSM-5 makes Marshall's therapist more likely to suggest appropriate treatment because, the DSM-5  suggests therapies or treatments for disorders included in it, while disorders that are not included in this document might be difficult to diagnose or treat due to lack of parameters or information about them.
