To apply the critical ratio rule, we need to calculate the critical ratio for each job:

Job A: (6-0)/6 = 1
Job B: (4-0)/4 = 1
Job C: (8-0)/8 = 1
Job D: (10-0)/10 = 1

All jobs have the same critical ratio, which means we should prioritize the shortest job, which is D. Among the remaining three jobs, we continue to prioritize the shortest one, which is C. 
So the sequence of jobs processed at Q45 should be: D-C-B-A. 
Therefore, the correct answer is C.
