(4 pts) Given a set of 3 periodic processes as shown below:

Process	Arrival Time	Period	Burst Time
$P_1$	0	30	10
$P_2$	10	70	10
$P_3$	20	100	20

Perform the rate-monotonic scheduling. Select correct description(s).

（複選；至少一個正確選項，每個選項獨立計分。）

(A)
The worst-case turnaround time (from the arrival time to the time of the completion of a process) of $P_2$ is 10.
(B)
The worst-case turnaround time of $P_3$ is 30.
(C)
If we increase the burst time of $P_3$ by X time units, the worst-case turnaround time of $P_3$ will also be increased by X time units.
(D)
If we change the arrival time of a process, the worst-case turnaround times of all processes will be the same.
