Find the Inverse of the Matrix $$\left[ \begin{array} { r r } 0 & - 3 \\- 3 & - 6\end{array} \right]$$

Find the inverse of the matrix.
- $$\left[ \begin{array} { r r } 0 & - 3 \\- 3 & - 6\end{array} \right]$$

A) $\left[ \begin{array} { l l } \frac { 2 } { 3 } & \frac { 1 } { 3 } \\ \frac { 1 } { 3 } & 0 \end{array} \right]$

B) $\left[ \begin{array} { r r } - \frac { 1 } { 3 } & 0 \\ \frac { 2 } { 3 } & - \frac { 1 } { 3 } \end{array} \right]$

C) $\left[ \begin{array} { r r } 0 & - \frac { 1 } { 3 } \\ - \frac { 1 } { 3 } & \frac { 2 } { 3 } \end{array} \right]$

D) $\left[ \begin{array} { r r } \frac { 2 } { 3 } - \frac { 1 } { 3 } \\ - \frac { 1 } { 3 } & 0 \end{array} \right]$
