Which of the following is a function of the operating system regarding processes?

The operating system plays a crucial role in managing processes, and all the functions listed are integral to this task.

Creating new processes is essential as it allows the system to execute multiple programs simultaneously. This is typically managed by the operating system, which allocates necessary resources and sets up execution contexts for the new processes.

Assigning CPU time management is another vital function of the operating system. In a multitasking environment, the OS must manage how much CPU time each process gets to ensure efficient use of resources and maintain system responsiveness.

Terminating processes is also a key responsibility of the operating system. It involves safely ending processes that are no longer needed or have completed their execution, ensuring that system resources can be released and reallocated for other processes.

Since all these functions contribute collectively to process management in an operating system, the correct answer encompasses the whole range of these essential operations.
