C. a reflection across the x-axis, and then a dilation by a scale factor of 2
Step-by-step explanation:
We see that the shapes are on the opposite sides of the x-axis, and vertical lines are still vertical. A 90° rotation would have made the vertical lines horizontal.
We see that the line that was 1 unit long is now 2 units. The line that went from 4 to 6 goes from 8 to 12. This is evidence of a dilation bt a factor of 2.
