Correct answer: B

In preemptive Priority Scheduling, each process is assigned a specific priority value. If a new process enters the ready queue with a higher priority than the one currently running, the operating system immediately interrupts (preempts) the lower-priority task and hands CPU control to the higher-priority process.
