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 `renice` command with the `-n` option sets the nice value (priority), and the `-p` option specifies the Process ID (PID). To set the priority to 0 for a process with PID 8481, the correct command is `renice -n 0 -p 8481`.

This choice is empty and provides no command.

The syntax `renice -p 0 ~n 8481` is incorrect; the nice level should be specified with `-n` followed by the value, and the PID with `-p` followed by the PID.

The command `renice -n 8481` is syntactically incorrect as it attempts to set the nice value to 8481 (which is outside the valid range of -20 to 19) and does not specify a target PID.
