Option D: System Bus
The system bus is responsible for connecting the CPU to external devices such as RAM and peripherals. It facilitates the transfer of data between these components, including addresses and control signals.

Option A: Control Bus
The control bus carries control signals that direct and coordinate activities within the computer's internal operations, such as memory access and I/O operations.

Option B: Address Bus
The address bus is used by the CPU to specify the address of a memory location or an I/O port. It is used for directing where data should be read from or written to.

Option C: Data Bus
The data bus is responsible for carrying data between the CPU, memory, and peripherals. It transfers actual data that needs to be processed or stored.

Conclusion:
Among the options provided, Option D: System Bus specifically refers to the bus that connects the CPU to external devices like RAM and peripherals, enabling data transfer and communication across the entire computer system.
