(C) The cofactors $C_{ij}$ of an element $a_{ij}$ are given by $C_{ij} = (-1)^{i+j} M_{ij}$,where $M_{ij}$ is the minor of the element $a_{ij}$.For the $2^{nd}$ row $(i=2)$:$C_{21} = (-1)^{2+1} \begin{vmatrix} 6 & 3 \ -7 & 3 \end{vmatrix} = -1 	imes (18 - (-21)) = -1 	imes (18 + 21) = -39$.$C_{22} = (-1)^{2+2} \begin{vmatrix} 5 & 3 \ -4 & 3 \end{vmatrix} = 1 	imes (15 - (-12)) = 1 	imes (15 + 12) = 27$.$C_{23} = (-1)^{2+3} \begin{vmatrix} 5 & 6 \ -4 & -7 \end{vmatrix} = -1 	imes (-35 - (-24)) = -1 	imes (-35 + 24) = -1 	imes (-11) = 11$.Thus,the cofactors are $-39, 27, 11$.
