A - 1, B - 2, C - 3, D - 4 Explanation: A. CPU Utilization 1 (Maximize - Keep CPU as busy as possible): CPU utilization measures how active the CPU is. An optimal operating system maximizes CPU usage to ensure hardware resources are fully leveraged. B. Throughput 2 (Maximize - Number of completed processes per time unit): Throughput is the number of processes completed per unit of time. Higher throughput means more work gets executed, so it should be maximized. C. Turnaround Time 3 (Minimize - Total time from submission to completion): Turnaround time measures the total interval from process submission to its completion. A efficient system strives to minimize this delay. D. Waiting Time 4 (Minimize - Total time spent sitting in the ready queue): Waiting time is the total amount of time a process spends waiting in the ready queue
