Homework: Section 3.1 < 20 4 3 4 3 05 Question 1, 3.1.1 Part 1 of 2 HW Score: 70.37%, 6.33 of 9 points O Points: 0 of 1 Compute the determinant using a cofactor expansion across the first row. Also compute the determinant by a cofactor expansion down the second column. CIB Save 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)(-23) + (0)(-6)-(4)(15)= O B. Using this expansion, the determinant is (2)(-23)-(0)(-6) + (4)(15)= O C. Using this expansion, the determinant is (0)(-6)-(4)(-4) + (5)(-6)= O D. Using this expansion, the determinant is -(0)(-6) + (4)(-4) - (5)(-6)=
