Multiple Choice

Find the matrix product AB, if it is defined.
- $$A = \left[ \begin{array} { r r r } 1 & 3 & - 1 \\3 & 0 & 5\end{array} \right] , B = \left[ \begin{array} { r r } 3 & 0 \\- 1 & 1 \\0 & 5\end{array} \right]$$

A)
$\left[ \begin{array} { l l } 0 & - 2 \\ 9 & 25 \end{array} \right]$

B)

$\left[ \begin{array} { c c } - 2 & 0 \\ 25 & 9 \end{array} \right]$

C) $\mathrm { AB }$ is undefined.

D)
$$\left[ \begin{array} { r r r } 3 & - 3 & 0 \\0 & 0 & 25\end{array} \right]$$
