Perform the Matrix Multiplication $A = \left[ \begin{array} { l l l } 0 & - 3 & 1 \\ 5 & - 1 & 0 \end{array} \right]$

Perform the matrix multiplication.
-Let $A = \left[ \begin{array} { l l l } 0 & - 3 & 1 \\ 5 & - 1 & 0 \end{array} \right]$ and $B = \left[ \begin{array} { r r } 1 & 2 \\ 0 & 1 \\ 1 & - 1 \end{array} \right]$ . Find $A B$ .

A) $\left[ \begin{array} { l r } 1 & 5 \\ - 4 & 9 \end{array} \right]$

B) $\left[ \begin{array} { c c } 0 & 10 \\ 0 & - 1 \\ 0 & 0 \end{array} \right]$

C) $\left[ \begin{array} { r r } 1 & - 4 \\ 5 & 9 \end{array} \right]$

D) $\left[ \begin{array} { l l l } 10 & - 5 & 1 \\ 5 & - 1 & 0 \\ - 5 & - 2 & 0 \end{array} \right]$
