Hint
Recollect about the radioactive decay process when a nucleus is in an excited state. It will be a gamma particle and when electrons go from one energy state to another they emit certain wavelengths of rays known as X- Rays.
Complete step by step answer
The essential distinction between $ \;\gamma - rays\; $ and X-rays is that $ \;\gamma - rays\; $ emanate from the nucleus. This happens during the radioactive decay process. A nucleus in an excited state has some extra energy which may release energy via gamma emission.
Electrons transitioning into a lower atomic orbital may emit an x-ray. Electrons propagating through a material may be accelerated (slowed down) by the electric field of a nucleus and will emit an x-ray. X-rays directly by accelerating a beam of electrons into a high atomic number metal, typically tungsten. The electrons are accelerated either by potential difference in x-ray tubes.
Option (B) is correct.
Note
i) Machine produced x-rays consist of a spectrum of energies, whereas gammas from a particular radionuclide have discrete energies..
ii) The term X-ray is used for photons with energies of about 1 keV and up that usually, but not always, come from man-made machines. Similarly, X-rays come from one of several processes that usually, but not always, involve electrons.
