Thanks for Invitation Mr. Ali.

Autocad supported255 Entity Colors. (Option - C-255).

I believe choice (D) Unlimited

I wuld say that acad can support unlimited entities colo,r that when you chose HSL and navigate croser in the HSL box in all directions  you can get unlimited entity color

AutoCAD supports "255 index colors" and many more can be created, however it is not unlimited
