Compute the determinant using a cofactor expansion across the first row. Also compute the determinant by a cofactor expansion down the second column. 2 0 3 2 4 3 0 4 -2 Compute the determinant using a cofactor expansion across the first row. Select the correct choice below and fill in the answer box to complete your choice (Simplify your answer.) O A. Using this expansion, the determinant is (2)(- 20) - (0)(-4) + (3)(8) = O B. Using this expansion, the determinant is (0)(- 4)- (4)(-4) + (4)(0) = Oc. Using this expansion, the determinant is - (2)(- 20) + (0)(-4)- (3)(8) = O D. Using this expansion, the determinant is - (0)(- 4) + (4)(-4)-(4)(0) =
