This one is really a definition, but here it is

In the production of X-rays, the term "bremsstrahlung" refers to which of the following:

A) The cut-off wavelength of the X-ray tube.

B) The discrete X-ray lines emitted when an electron in an outer orbit fills a vacancy in an inner orbit of the atoms in the target metal of the X-ray tube.

C) The discrete X-ray lines absorbed when an electron in an inner orbit fills a vacancy in an outer orbit of the atoms in the target metal of the X-ray tube.

D) The smooth, continuous X-ray spectra produced by high-energy blackbody radiation from the X-ray tube.

E) The smooth, continuous X-ray spectra produced by rapidly decelerating electrons in the target metal of the X-ray tube.
