I think you forgot to put a picture
The biggest problem with ms. Parisi's arrangement is "<span>She will not be able to see the entire class from where she is seated."
Because when she puts her desk at the center of the class and students are sitting around her in a circle, She will not be able to see all of her students, she will be able to see only students who are sitting in front of her.</span>
Really, it's C, because A and B are actually the opposite of what happened.
Idk sorry I would help you but I didn’t do that one
