Which ones of the following linear transformations are NOT invertible? (Choose one or more)Question 12Select one or more:a.A𝐴 transforms the unit square [0,1]×[0,1][0,1]×[0,1] into a point (0,0)(0,0).b.A𝐴 transforms the unit square [0,1]×[0,1][0,1]×[0,1] into a square with vertices (0,0)(0,0), (2,0)(2,0), (1,1)(1,1), and (1,−1)(1,−1).c.A𝐴 transforms the unit square [0,1]×[0,1][0,1]×[0,1] into a rectangle with vertices (0,0)(0,0), (2,0)(2,0), (0,5)(0,5), and (2,5)(2,5).d.A𝐴 transforms the unit square [0,1]×[0,1][0,1]×[0,1] into the line segment from (0,0)(0,0) to (1,3)(1,3).
