c. Both a and b

Explanation:

When we define an Operating System we say that it is a software that allows you to control the basic processes of a computer and allow the operation of other programs, that is, its function is to manage the physical resources of the computer so that they optimally execute other programs.

For example, when we open a program that is on the desktop, we click with the mouse (which is an input device) on an icon that we see on the monitor (which is an output device), and the program opens, which we see on the screen, and this program is executed by writing and reading operations in both secondary storage units and RAM, processing information through the CPU.

The previous example shows the task of the Operating System, which is nothing more than managing all the resources of the computer according to the own requirements or of other programs installed in the computer, managing the services that these require. also, the operating system can limit or enable functions of any software on the computer, they could not run without the existence of the OS. This is why the Operating System is the most important software of any computer.
