Consider the following tasks, with period and worst$-$case execution time $($WCET$)$ shown:

Period $($ms$)$

WCET $($ms$)$

Task A

$10$

$5$

Task B

$20$

$2$

Task C

$20$

$2$

Task D

$40$

$5$

Decide whether each statement about scheduling these tasks is true of false and choose the appropriate option. However, don't choose either option if you are unsure as incorrect choices lose marks.
