Using the critical ratio dispatching rule, we calculate the critical ratio for each job as follows:
Job A: CR = (4 - 0) / 6 = 0.67
Job B: CR = (3 - 1) / 5 = 0.4
Job C: CR = (7 - 2) / 10 = 0.5
Job D: CR = (6 - 3) / 8 = 0.38
Job E: CR = (5 - 4) / 9 = 0.11

The critical ratio is the ratio of time remaining until the due date to the processing time. The higher the critical ratio, the greater the urgency of the job.

Based on these calculations, we should prioritize the jobs in the following order:
B, C, A, D, E

Therefore, the correct answer is B: C, D, A, B, E.
