Answer:
B) a rotation, then a reflection.
Step-by-step explanation:
From the given graph, the white shape transformed into blue shape.
If you look at the white shape and the blue shape.
The white shape rotated 45° counter clock wise and reflected over the origin x = y to get the blue figure.
For example, let's take a vertex (2, -1) in the white figure. The corresponding in the blue shape is (-2, 1) which is reflection about the origin.
Therefore the answer is B) a rotation, then a reflection.
