Assume that OS implements a scheduling policy: It selects a process in Round Robin fashion, runs the process for a maximum of $10$ milliseconds or until the process blocks or terminates itself before $10$ milliseconds. Which of the following statements is$/$are true about this scheduling policy? Justify for each option.

$($a$)$ It cannot be efficiently implemented without hardware support for timer interrupts.

$($b$)$ It is an example of a non$-$preemptive

scheduling policy.

$($c$)$ It can sometimes result in involuntary context switches.

$($d$)$ It prioritizes processes with shorter CPU burst times over processes that run for long durations.
