Q$22$: Assuming the following system of four processes P$1,$ P$2,$ P$3,$ P$4$ being scheduled with the round robin $($RR$)$ scheduling algorithm.

The processes have the following CPU burst time.

$P1=10$

$P2=4$

$P3=5$

$P4=3$

The processes arrival time is as the following.

$P1=0$

$P2=1$

$P3=2$

$P4=3$

$($quantum $=4)$

The waiting time for $P3$ is$?$

a$.3$

b$.9$

c$.13$

d$.12$

e$.11$
