Multiple Choice

Find the minor $M _ { 13 }$ and its cofactor $C _ { 13 }$ of the matrix $\left[ \begin{array} { c c c } - 3 & 2 & - 8 \\ 3 & - 2 & 6 \\ - 1 & 3 & - 6 \end{array} \right]$ .

A)
$M _ { 13 } = \left| \begin{array} { c c } - 3 & - 8 \\ - 1 & - 6 \end{array} \right| = 10$
$C _ { 13 } = - 10$

B)
$M _ { 13 } = \left| \begin{array} { c c } 2 & - 8 \\ - 2 & 6 \end{array} \right| = - 4$
$C _ { 13 } = - 4$

C)
$M _ { 13 } = \left| \begin{array} { c c } 3 & - 2 \\ - 1 & 3 \end{array} \right| = 7$
$C _ { 13 } = - 7$

D)
$M _ { 13 } = \left| \begin{array} { c c } 2 & - 8 \\ - 2 & 6 \end{array} \right| = - 4$
$C _ { 13 } = 4$

E)
$$\begin{array} { l } M _ { 13 } = \left| \begin{array} { c c } 3 & - 2 \\- 1 & 3\end{array} \right| = 7 \\C _ { 13 } = 7\end{array}$$
