Traditionally, an Expert Would Not Testify Directly on Whether a Defendant

Traditionally, an expert would not testify directly on whether a defendant was unfit to stand trial or NCRMD; instead they were only to address three questions. Which is NOT one of those questions?

A) How did the defendant's symptoms of mental disorder influence the offence behaviour?
B) Does the accused have a specific mental disorder?
C) What is the likelihood that the person will be effectively treated and no longer pose a threat to society?
D) How do the symptoms of mental disorder impair the ability of the accused to understand the proceedings?
