During the Process of Coherent Scattering,an Incident Low-Energy X-Ray Photon

During the process of coherent scattering,an incident low-energy x-ray photon interacts with

A) a single inner-shell electron,ejecting it from its orbit.
B) a single outer-shell electron,ejecting it from its orbit.
C) an atom and may transfer its energy by causing some or all of the electrons of the atom to momentarily vibrate and radiate energy in the form of electromagnetic waves.
D) a scattered photon of lesser energy,annihilating it.
