An Electron Moving in a Magnetic Field in Space Is

An electron moving in a magnetic field in space is forced to move in a spiral pattern. As it does so, it emits

A) characteristic X-rays as the electron is slowed down by this motion.
B) visible light, mostly blue in color because the electron is forced to move in a circular path.
C) synchrotron radiation, mostly radio waves, since the electrons are accelerating.
D) nothing since such electrons are moving with a constant speed and are not therefore accelerating.
