The table below displays the EST$-$ECT LCT$-$LST information for a project. $($The time is measured by a unit of day.$)$

$\backslash$table$[[,$A$,$B$,$C$,$D$,$E$,$F$,$G$],[$EST$,0,2,2,9,6,6,],[$ECT$,2,9,6,15,8,10,],[$LCT$,2,9,7,15,9,10,13],[$LST$,0,2,3,9,7,12,15]]$

Please use the information in the table to decide which option$($s$)$ is $($are$)$ CORRECT. $($Difficulty Level $-$ Hard$)$

There may be more than one correct choice. Select ALL that apply.

To avoid delaying the completion of the project, activity $C$ has to start no later than day $2.$
