A)
$\left[ \begin{array} { r r } 0 & - 1 \\ - \frac { 1 } { 5 } & - \frac { 4 } { 5 } \end{array} \right]$
B)
$\left[ \begin{array} { c c } 0 & 1 \\ \frac { 1 } { 5 } - \frac { 4 } { 5 } \end{array} \right]$
C)
$\left[ \begin{array} { c } - \frac { 4 } { 5 } 1 \\ \frac { 1 } { 5 } 0 \end{array} \right]$
D)
$\left[ \begin{array} { c c } \frac { 1 } { 5 } - \frac { 4 } { 5 } \\ 0 & 1 \end{array} \right]$
