The correct answer is:
Bus arbitration is the process used to regulate access to the system bus in a microprocessor. It ensures that multiple devices do not try to use the bus simultaneously, which could lead to conflicts or data corruption. Bus arbitration uses control signals to manage which device can use the bus at any given time, preventing two devices from accessing it at once.
