Write the Augmented Matrix for the System $\begin{aligned}3 x+5 y & &=8 \\-5 y-8 z &=4 \\-3 z &=-9\end{aligned}$

Write the augmented matrix for the system. Do not solve the system.
- $\begin{aligned}3 x+5 y & &=8 \\-5 y-8 z &=4 \\-3 z &=-9\end{aligned}$

A)
$\left[ \begin{array} { r r r | r } 3 & 5 & 8 & 0 \\ - 5 & - 8 & 0 & 4 \\ - 3 & 0 & 0 & - 9 \end{array} \right]$

B)
$\left[ \begin{array} { r r r | r } 3 & 5 & 8 & 0 \\ - 5 & - 8 & 4 & 0 \\ - 3 & - 9 & 0 & 0 \end{array} \right]$

C)
$\left[ \begin{array} { r r r | r } 3 & 5 & 0 & 8 \\ - 5 & - 8 & 0 & 4 \\ - 9 & 0 & 0 & - 9 \end{array} \right]$

D)
$\left[ \begin{array} { r r r | r } 3 & 5 & 0 & 8 \\ 0 & - 5 & - 8 & 4 \\ 0 & 0 & - 3 & - 9 \end{array} \right]$
