Find the reverse operation that transforms the second matrix into the first. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. Replace row 3 by its sum with times row 1. (Type an integer or a simplified fraction.) O B. Interchange row 3 and row 2. O C. Scale row 3 by (Type an integer or a simplified fraction.) O D. Replace row 3 by its sum with times row 2. (Type an integer or a simplified fraction.)Find the elementary row operation that transforms the first matrix into the second, and then find the reverse row operation that transforms the second matrix into the first. - 2 1 0 - 2 1 0 3 -2 3 -6 0 4 0 - 6 0 3 -2 7 0 3 -2 7 . . .
