There are 10 different processes running on a workstation. Idle processes are waiting for an input event in the input queue. Busy processes are scheduled with the Round-Robin time sharing method. Which out of the following quantum times is the best value for small response times, if the processes have a short runtime, e.g. less than 10ms?

• A. tQ = 15ms
• B. tQ = 40ms
• C. tQ = 45ms
• D. tQ = 50ms
