B)Increase the coefficient of variation of job arrival times.
C)Increase the coefficient of variation of job processing times.
D)None of these would decrease waiting time.

Decreasing utilization (the ratio of the time that a resource is actually used to the time that it is available for use) directly reduces the waiting time in a process. Lower utilization means that resources are less busy and can handle incoming jobs more quickly, thus reducing the waiting time. Increasing the variability in arrival or processing times (options B and C) would typically increase waiting times, not decrease them, because it makes the process less predictable and harder to manage efficiently.
