A junior Linux administrator is optimizing a system in which an application needs to take priority 0 when running the process. The administrator runs the ps command and receives the following…

The command renice -n 0 -p 8481 correctly uses the -n flag to specify the target nice value of 0 and the -p flag to target the process by its PID 8481. This is the proper renice syntax for setting a specific nice value on a running process identified by PID.

renice -p 8481 omits the required -n flag and nice value argument, so the command lacks the information needed to change the process priority.

The command text is absent from this choice and cannot be evaluated.

renice -n 8481 incorrectly uses the PID as the nice value argument, and 8481 is far outside the valid nice value range of -20 to 19.
