If$\text{A}=\begin{vmatrix}\text{a}_{11}&\text{a}_{12}&\text{a}_{13}\\\text{a}_{21}&\text{a}_{22}&\text{a}_{23}\\\text{a}_{31}&\text{a}_{32}&\text{a}_{33}\end{vmatrix}$ and $C_{ij}$ is cofactor of $a_{ij}$ in a, then value of $|A|$ is given by:

• A
  $a_{11}C_{31} + a_{12}C_{32} + a_{13}C_{33}$
• B
  $a_{11}C_{11} + a_{12}C_{21} + a_{13}C_{31}$
• C
  $a_{21}C_{11} + a_{22}C_{12} + a_{23}C_{13}$
• ✓
  $a_{11}C_{11} + a_{21}C_{21} + a_{13}C_{31}$
