Selected Answer: D
When a process is started using the `nice` command, the default nice level is: D. 0 A nice level of 0 represents the default priority, meaning the process is initially running with normal scheduling priority. Positive nice values make a process less favorable, while negative values make a process more favorable in terms of CPU scheduling. The default nice level of 0 is considered the normal or neutral priority.

Selected Answer: D
A niceness of -20 is the lowest niceness, or highest priority. The default niceness for processes is inherited from its parent process and is usually 0. Systems have diverged on what priority is the lowest. Linux systems document a niceness of 19 as the lowest priority, BSD systems document 20 as the lowest priority.
