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)-9) + (1X-8) - (5)X-6)=
OB. Using this expansion, the determinant is (2x-17)-(-2X-9)+ (4X(14) =
OC. Using this expansion, the determinant is - (2) - 17)+(-2X-9)-(4)(14) =
OD. Using this expansion, the determinant is (- 2X -9)-(1x-8) + (5) -6) =
