C Correct answer
Explanation

The Data Bus is bidirectional because it carries data both from the CPU to memory/devices (write operations) and from memory/devices to the CPU (read operations). The Address Bus is unidirectional (CPU to memory, carrying address information), and the Control Bus carries signals in one direction at a time (CPU controlling devices or status signals back to CPU).
