B seems the most logical

B is correct becuase the way astronomers find planets is that they observe a star for quite some time and if they see dips meaning a time when light is blocked they will see that there is something there once they see this dip they check and see if it has a pattern to it and if so they determine it is a planet.... I just love astronomy xD
