Find the Indicated Matrix $A = \left[ \begin{array} { r r } - 1 & 3 \\ 0 & 4 \\ 8 & - 4 \end{array} \right]$

Find the indicated matrix.
-Let $A = \left[ \begin{array} { r r } - 1 & 3 \\ 0 & 4 \\ 8 & - 4 \end{array} \right]$ and $B = \left[ \begin{array} { r r } 7 & 2 \\ 17 & 4 \\ 3 & 2 \end{array} \right]$ . Find $A - B$

A) $\left[ \begin{array} { r r } 1 & 1 \\ 7 & 0 \\ 5 & - 2 \end{array} \right]$
B) $\left[ \begin{array} { r r } 1 & 4 \\ 7 & 8 \\ 11 & 1 \end{array} \right]$
C) $\left[ \begin{array} { r r } 3 & - 2 \\ 7 & 0 \\ - 5 & 6 \end{array} \right]$
D) $\left[ \begin{array} { r r } - 8 & 1 \\ - 17 & 0 \\ 5 & - 6 \end{array} \right]$
