If $\Delta = \begin{vmatrix} a_11&a_12&a_13 \\ a_21&a_22&a_23 \\ a_31&a_32&a_33 \end{vmatrix} $ and $A_y$ is Cofactor of $a_y$, then value of $\Delta$ is:

Question

\[ \begin{array}{l} (A) \quad a_{11}A_{31}+a_{12}A_{32}+a_{13}A_{33} & (B) \quad a_{11}A_{11}+a_{12}A_{21}+a_{13}A_{31} \\(C) \quad a_{21}A_{11}+a_{22}A_{12}+a_{23}A_{13} & (D) \quad a_{11}A_{11}+a_{21}A_{21}+a_{31}A_{31} \\\end{array} \]
