The transformation on the figure is a reflection over the y-axis.
How to identify the transformation?
In the image, we can see that we have an original figure in the left side of the y-axis, and then it is reflected over it.
We can see that it is a reflection and not a translation, because the orientation of the figure changes (you can see that in both figures, the 90° is in the side farthest away from the axis).
So the correct option is B, reflection over the y-axis.
