The Matrices a and B Are Defined as Follows: a =

The matrices A and B are defined as follows: A = $\left( \begin{array} { r r } 4 & 5 \\- 1 & 6\end{array} \right)$ , B = $\left( \begin{array} { r r } 1 & - 1 \\2 & 0\end{array} \right)$ Carry out the indicated matrix operation.
A + B

A) $\left( \begin{array} { l l } 5 & 4 \\1 & 6\end{array} \right)$
B) $\left( \begin{array} { l l } 1 & 5 \\5 & 6\end{array} \right)$
C) $\left( \begin{array} { l l } 5 & 6 \\1 & 4\end{array} \right)$
D) $\left( \begin{array} { l l } 5 & 4 \\1 & 7\end{array} \right)$
E) $\left( \begin{array} { l l } 5 & 1 \\1 & 5\end{array} \right)$
