The following code does not work properly for all the following reasons, except: projectData $\%>\%$

arrange$($desc$($investment$))+$

select$($status $==$ "completed"$)$

$$ The select function is used for selecting columns, not for filtering rows based on conditions

The arrange function cannot be used with the desc$()$ function at the same time

The $+$ operator is not used properly to sequence data management tasks

All of the above are correct reasons why the code does not work
