Note, only Windows really cares about the file extension. OSX's Finder will use it if Finder can't find a creator in the file metadata to select an app when double clicking on it. Linux and Unix don't care.
Answer:
Correct option is
A. She can add a digitizer over the screen on her laptop
Explanation:
A digitizer is a hardware that receives analogue signal and converts is to digital signal.To use stylus on a normal laptop when can attach a digitizer to the laptop.These digitizer comes in form of Tablet (Graphics Tablet)
Graphics tablet is an external tablet like slate with a dedicated stylus for hand drawn designing and arts. Use of stylus gives more command over design features.It can read any kind of hand written data and transfer to PC.
