Concept:The operating system manages the computer's hardware and software resources.
Explanation:Every computer has components such as the processor, memory, and storage devices.
These components need instructions to work together correctly.
The operating system gives these instructions and controls the hardware.
It tells the computer how to use each component, like reading from memory or saving data to disk.
It also runs applications and allocates resources to them.
Without an operating system, the computer cannot coordinate its own parts.
Utility programs, application software, and networks do not perform this central management role.
Therefore, the correct answer is the operating system.
Answer:C. operating system
