The correct option is B CPU

An Operating System (OS) is an interface between a computer user and computer hardware. An operating system is a software which performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers.

The CPU is the Central Processing Unit. ... Some specific calcuations, such as those necessary to produce sound or graphics, are delegated to specific components, but the CPU is ultimately the "brain" of your computer. An Operating System is the core software that allows applications to interface with the hardware.

The physical connections that carry control information between the CPU and other devices within the computer. Whereas the data bus carries actual data that is being processed, the control bus carries signals that report the status of various devices.
