A. RRExplanation
The correct answer is RR (Round Robin). The Round Robin scheduling algorithm is the best in terms of Average Turn-Around Time (ATAT) because it ensures fairness in the allocation of CPU time to all processes. In Round Robin, each process is given a fixed time slice or quantum, and if a process does not complete within its time slice, it is moved to the back of the queue and the next process is given a chance to execute. This prevents any single process from monopolizing the CPU and leads to a balanced distribution of CPU time among all processes, resulting in a lower average turn-around time.Rate this question:
