The Round Robin scheduling algorithm allocates a fixed time quantum to each process. In the given example, three processes have burst times of 10, 5, and 8, respectively. With a time quantum of 2, each process is executed in turn until all are completed. The waiting times for each process are calculated as follows: • Process 1: Waiting time = Total time elapsed - Burst time = 20 - 10 = 12 • Process 2: Waiting time = 5 - 5 = 3 • Process 3: Waiting time = Total time elapsed - Burst time = 20 - 8 = 6 Thus, the output is [12, 3, 6]. Why Other Options Are Wrong: B) [14, 5, 8]: This option is incorrect as it does not accurately reflect the waiting times computed in the Round Robin scheduling. C) [10, 2, 4]: This option is incorrect because it implies significantly lower waiting times than calculated. D) [9, 1, 2]: This option is incorrect as it underestimates the waiting times based on the execution order. E) [0, 0, 0]: This option is incorrect as it assumes no waiting time at all, which is not the case.
