Can someone please explain to me ASAP??!!

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 4 3 4 2 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)( - 16) - (0)( -6) + (4)(12) = O B. Using this expansion, the determinant is - (2)( - 16) + (0)( -6) -(4)(12) = O C. Using this expansion, the determinant is (0)( - 6) - (4)( -4) + (4)(-8) = O D. Using this expansion, the determinant is - (0)( - 6) +(4)( -4) - (4)( -8) =
