Answer:
The option which best describes the plea that George's defense attorney made is:
C. Not guilty by reason of insanity
Step-by-step explanation:
What George's attorney is doing is he is admitting that George did kill his children but, while doing that, he was incapacitated or mentally disturbed. That means he cannot be held responsible and seen as guilty, since he did not have the intention of committing a crime. By definition, this plea is consistent with "not guilty by reason of insanity".
