A user's track pad has stopped working. Which of the following should the user do to resolve the track pad's functionality?

Reinstalling mouse drivers is a more advanced troubleshooting step, typically done after checking basic settings and if driver corruption is suspected, and trackpads often have specific drivers, not generic 'mouse' drivers.

While some laptops have a Function (Fn) key combination to enable/disable the trackpad, checking the OS settings is a more universal initial step for trackpad functionality issues.

Calibrating a digitizer is relevant for touchscreens or pen input devices, not a standard trackpad.

The mouse or trackpad settings in the operating system often include options to enable/disable the trackpad, adjust its sensitivity, and configure gestures. Checking these settings first can quickly resolve issues where the trackpad was accidentally disabled or its configuration became corrupted.
