Why Other Options are Wrong: a) SJF minimizes waiting time since shorter jobs are processed first. b) Starvation can occur if shorter jobs keep arriving, delaying longer ones indefinitely. c) It is optimal when job lengths are known in advance. e) SJF focuses on minimizing turnaround and waiting time
