What devices are plugged into the motherboard?

The correct choice identifies the critical components that interact directly with the motherboard, which is the central communications hub in a computer. The CPU, or Central Processing Unit, is often referred to as the brain of the computer, executing instructions and performing calculations. ROM chips, which contain read-only memory, play a vital role in storing firmware and system management data essential for the computer's boot process and essential operations.

Interface cards, such as graphics cards, sound cards, and network cards, expand the functionality of the computer by allowing it to connect with various peripherals and enhancing processing capacity for specific tasks. These components require a direct connection to the motherboard to function, making their inclusion in this option accurate.

The other options do not cover the full range of critical elements that connect to the motherboard. Cooling fans, while important for maintaining optimal temperatures, do not fundamentally contribute to the computing processes like the CPU, ROM chips, and interface cards do. Limiting the focus to only storage drives or only cooling devices excludes significant parts of the system that are essential for operation and performance.
