Select the correct choice below and fill in the answer box to complete your choice. (Simplify your answer.) A. Using this expansion, the determinant is (2)(-20) (0) (-6)+(3)(12)= -4 OB. Using this expansion, the determinant is -(2)(-20)+(0)(-6)-(3)(12)= OC. Using this expansion, the determinant is - (0)(-6)+(4)(-4) - (4)( -3)= D. Using this expansion, the determinant is (0) (-6) - (4)(-4)+(4)(-3)= Compute the determinant using a cofactor expansion down the second column. Select the correct choice below and fill in the answer box to complete your choice. (Simplify your answer.) OA. Using this expansion, the determinant is - (0)(-6)+(4)( -4) - (4)( -3)= | OB. Using this expansion, the determinant is (2)(-20)-(0)(-6)+(3)(12)= | OC. Using this expansion, the determinant is (0)(-6) - (4)(-4)+(4)( -3)= | OD. Using this expansion, the determinant is - (2)(-20)+(0)(-6)-(3)(12)=
