- $$A = \left[ \begin{array} { l l } 0 & - 3 \\4 & - 3\end{array} \right]$$

A)
$$\left[ \begin{array} { c c } - \frac { 1 } { 4 } & - \frac { 1 } { 4 } \\\frac { 1 } { 3 } & 0\end{array} \right]$$
B)
$$\left[ \begin{array} { r r } 0 & \frac { 1 } { 4 } \\- \frac { 1 } { 3 } & - \frac { 1 } { 4 }\end{array} \right]$$
C) Inverse does not exist
D)
$$\left[ \begin{array} { l l } - \frac { 1 } { 4 } & \frac { 1 } { 4 } \\- \frac { 1 } { 3 } & 0\end{array} \right]$$
