B) Will probably not have more damage than if he came in immediately
C) Can have restoration of the area of dead cells with proper treatment
D) Has been damaged already, so immediate treatment is no longer necessary
Ans: A

Despite the length of time the symptoms have been present, treatment needs to be initiated immediately to minimize further damage.
