What is the function of the motherboard in a computer?

The motherboard serves as the central hub of a computer system, playing a critical role in supporting all major components and facilitating communication among them. It connects the CPU, RAM, storage devices, and various expansion cards, allowing for a cohesive operation of hardware components.

In addition to providing the physical structure for connecting these parts, the motherboard includes the chipset, which manages data flow between the processor, memory, and peripherals. This ensures that data can move to and from various parts of the computer efficiently. By coordinating these interactions, the motherboard is essential for the overall functionality and performance of a computing system.

While managing power supply, enhancing graphics performance, and providing storage options are important functions in a computer, these are usually specific to other components such as the power supply unit, graphics card, and storage devices. The motherboard's primary role is to unite these elements into a working system, making option B the most accurate description of its function.
