Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

When a device is busy, you must find and terminate the processes accessing it. Option a describes this strategy, and option b provides the concrete implementation using fuser to identify and kill (-k) those processes before unmounting. Thus, both a and b are correct.
