The critical ratio rule is considered one of the best priority rules for scheduling because it takes both the due date and processing time into account. It is calculated by dividing the time between today and the due date by the processing time. The resulting ratio represents the urgency of the job and helps to prioritize the jobs accordingly. The smaller the ratio, the higher the urgency, and higher priority the job receives. Therefore, A) Critical Ratio is the best choice for sequencing jobs using the smallest ratio of due date from today to processing time.
