C
Control Bus
D
Data Bus
Correct Answer: Option D — Data Bus
Explanation:
The Data Bus is used to transfer actual data between the CPU, memory, and other hardware components. It carries information in both directions, allowing the processor to read data from memory and write data back to it. The width of the data bus affects how much data can be transferred at one time, influencing overall system performance and speed.
