Consider a Round Robin CPU scheduler with a time quantum of $4$ units. Let the process profile for this CPU scheduler be as follows:

ProcessArrival TimeCPU BurstP$1$t$9$P$2$t$+32$P$3$t$+57$P$4$t$+86$P$5$t$+115$P$6$t$+128$

Assume that at time t$,$ the CPU is idle and there are no processes in the ready queue when process P$1$ arrives. Determine the schedule of process execution, and compute the wait times for each of the six processes. Which of the following is TRUE about the average wait time and the average turnaround time for the six processes?

Question $2$ options:

Average wait time is between $11\mathrm{.}0$ and $15\mathrm{.}0$; average turnaround time is between $17\mathrm{.}0$ and $21\mathrm{.}0$

Average wait time is between $9\mathrm{.}0$ and $13\mathrm{.}0$; average turnaround time is between $17\mathrm{.}0$ and $21\mathrm{.}0$

Average wait time is between $14\mathrm{.}0$ and $18\mathrm{.}0$; average turnaround time is between $17\mathrm{.}0$ and $21\mathrm{.}0$

Average wait time is between $11\mathrm{.}0$ and $15\mathrm{.}0$; average turnaround time is between $20\mathrm{.}0$ and $24\mathrm{.}0$
