What is the bremsstrahlung process?

A. The emission of a photon from an electron being accelerated by a nucleus
B. The emission of an electron from a metal when light is shined on it
C. Thermal excitation of photons in a substance
D. The emission of an electron from an inner electron shell and the resulting photon when an electron drops from an outer shell to take its place
E. Converting power-producing nuclear material to weapons grade

A.
When an electron passes significantly close to a nucleus, the electron enters a relatively strong electric field. The electron accelerates (that is, changes speed and/or direction) in the field and emits a photon because all accelerating electrons emit photons.
