Multiple Choice

Find the inverse, if it exists, for the matrix.
- $\left[ \begin{array} { l l } 3 & 0 \\ 3 & 4 \end{array} \right]$

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