Answer:
B. reflection about the origin
Explanation:
When we look at this figure, we can see that this is not a 90 degree rotation in any direction; this would turn the figure 90 degrees, which would move the image in Quadrant II to either Quadrant I or Quadrant III instead of Quadrant IV.
A reflection across the x-axis will negate the y-coordinate, moving the image either directly above or directly below the pre-image. This is not the case, so this is not a reflection across the x-axis.
In a reflection about the origin, both the x- and y-coordinates are negated; this is the same as a 180 degree rotation. This would move the pre-image to match the image.
