Which technique prevents starvation of low-priority processes in priority scheduling?
Correct answer B. Aging, which gradually raises the priority of processes that wait a long time
Explanation
With strict priority scheduling, a steady stream of high-priority work can delay a low-priority process indefinitely. Aging fixes this by increasing a process's priority the longer it waits, so it eventually becomes the highest and runs. Changing the quantum does not affect who is chosen, and lowering waiting processes' priority would make starvation worse.
