When a gamma-ray photon undergoes pair production, what is one possibility for the final products?
A) an electron and a positron (the antielectron)
B) an electron and an antineutrino
C) a proton, an electron, and an antineutrino
D) two X-ray photons, each with half the energy of the original gamma ray

Pair production is a process where a gamma-ray photon, under the right conditions, can transform into a particle and its antiparticle pair. In this case, the correct pair is an electron and a positron (the antielectron). This process conserves both charge and energy.
