Compute the determinant using a cofactor expansion across the first row. Also compute the determinant by a cofactor expansion down the second column. 3 0 4 3 4 3 0 4 -1 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 (0)(- 3)– (4)(– 3) + (4)(- 3) = O B. Using this expansion, the determinant is - (0)(- 3)+ (4)(- 3)– (4)(– 3) = Oc. Using this expansion, the determinant is (3)(- 16) – (0)(- 3) + (4)(12) = O D. Using this expansion, the determinant is - (3)(– 16) + (0)(-3) – (4)(12)=

Compute the determinant using a cofactor expansion across the first row. Also compute the determinant by a cofactor expansion down the second column. 3 0 4 3 4 0 4 - 1 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 (0)(- 3)- (4)(- 3)+ (4)(– 3) = B. Using this expansion, the determinant is - (0)(- 3) + (4)(– 3) - (4)(– 3) = C. Using this expansion, the determinant is (3)(- 16) - (0)(- 3)+ (4)(12) = D. Using this expansion, the determinant is - (3)(- 16) + (0)(– 3) – (4)(12) =
