$($II$)(1$ Point$)$ Consider the following MATLAB script:

Line $1$: $n=0$:$4$;

Line $2$: $x=\left[\begin{array}{ccccc}0& 1& 1& 2& 5\end{array}\right]$;

Line $3$: $h=\left[\begin{array}{ccccc}2& 0& 1& 4& 3\end{array}\right]$;

Line $4$: $y=$conv$(x,h)$;

Line $5$: stem$(n,y)$;

Line $6$: xlabel $(\text{'}n\text{'})$;

Line $7$: ylabel $(\text{'}$y$[$n$]\text{'})$;

The above script will generate an error at:

$($a$)$ Line $1$

$($b$)$ Line $2$

$($c$)$ Line $3$

$($d$)$ Line $4$

$($e$)$ Line $5$

$($f$)$ Line $6$

$($g$)$ Line $7$
