b. Characteristic radiation emitted when an electron is displaced from the outer shell of a tungsten atom in the target 

c. the electromagnetic spectrum 

d. particulate radiation 

The correct answer is: A. a. the primary source of X-rays from an X-ray tube. 

BREMSSTRAHLUNG RADIATION: The sudden stopping or slowing of high-speed electrons by tungsten nuclei in the target produces bremsstrahlung photons, the primary source of radiation from an x-ray tube. (Bremsstrahlung means “braking radiation” in German.)
