A
Correct Answer
It monitors the system for unresponsiveness and automatically resets the device if the software fails to "check in" periodically, helping recover from hangs
Explanation
If the main program fails to reset ("feed") the watchdog timer within a set period (e.g., due to a crash or infinite loop), the watchdog triggers a system reset, improving reliability in unattended devices.
