An administrator notices that a backup process, which has a process ID (PID) of 2635, is consuming more resources than it should during peak hours, impacting the performance of other critical services on the server. The administrator decides to lower the priority of this backup process to minimize its impact on system performance. Which of the following commands should be used to change the niceness (priority) of the running process to a higher nice value, thereby giving it a lower scheduling priority, without stopping the process?
nice -5 -p 2635
renice -5 2635
nice --adjustment=+5 --pid=2635
renice +5 2635
