An exposure taken with an 80 kilovoltage peak (kVp) would have a maximum photon energy of:

Explanation:
The maximum photon energy in an x-ray beam is determined by the energy to which the electrons are accelerated, which is set by the peak tube voltage (kVp). An 80 kVp exposure accelerates electrons to energies up to about 80 keV. When these electrons are decelerated in the anode, the emitted photons can have energies anywhere from near zero up to this maximum, but cannot exceed it. So the highest-energy photons produced can have an energy of 80 keV. That’s why the correct choice is 80 keV.
