Answer: Choice B
270 degree rotation clockwise
=======================================================
Step-by-step explanation:
Notice that 270+90 = 360
Going 90 degrees in one direction is the same as going 270 degrees in the other direction because the two combine to a full 360 degree rotation.
Check out the image below for an example. In the example, the point P starts at (0,5). Doing either rotation mentioned will get us to (-5,0).
